I'm sure you'll be able to find a way to make the most of your time and money.

　The moment I overtook her, Lilith was
There's the man himself, Master Ike.
　I smiled.

''In a manner of speaking, I'm a magician in the Demon King's army. I don't want to lose to a magical swordsman.''

No, Master Ike is not just a magician. He's the most powerful magician in the Demon King's army.

　By the time he heard her sycophancy, he had completely overtaken Lilith and was approaching the Sea Serpent.
　The distance to the monster would be at least thirty meters.
　But at that point, the giant body of the Sea Serpent overwhelmed me.

''It's.......huge.''

　It was such a huge body that only such simple words could be used.

　In the Demon King's Army, large demons, such as the giant race, were often seen, but this might be the first time they had seen such a huge demon.

　Even in the previous life, the largest animal was a blue whale that lived in the sea.
　Perhaps the ocean, free from the yoke of gravity, is the place where giant creatures are easily born.
　At that moment, the Sea Serpent's massive body is enveloped by a tornado.
　If you look at it, the golden-haired elf floating at sea seems to have summoned the Spirit King.

''Ike-sama, what's that?''

"I think it's Garuda, the Spirit King of the Wind.

　Maybe, he continues, but.
　I'm not that knowledgeable when it comes to spirits.

　When I was young, my grandfather gave me knowledge other than magic, but according to my hazy knowledge, I've heard that spirits are divided into higher and lower species, and that the higher species are called spirit kings.

　I remember that the upper level spirit of the wind was 'Garuda', as I recall.

　He had the head of an eagle, the body of a human, and the wings of a bird, and could be considered the king of nature who rules the wind. It is said that only a high-ranking spirit user can control it, but Anemone seemed to be using it brilliantly.

''Surprisingly, Anemone can be used.

　Lilith sighs as she clicks her tongue lightly.

'She's a good-hearted girl. If you're dealing with a monster, you don't feel the need to go easy on it.'

You're just the kind of girl who's afraid of being upset.

　I'll be careful in the future, Lilith added, and watched the battle.
　I'll follow suit.
　The spirit king that Anemone had summoned transformed into a tornado and approached the Sea Serpent.
　The tornado that arose at sea carried sharp fangs like blades that cut through all things.
　The blade of the raging storm cut through the steel scales of the Sea Serpent.


''Goooooooo!


　A scream that was not of this world was spirited to the hit.
　It was so loud that it was as if the roar he had just heard sounded like the chirping of a little bird.

''It works........you're here, aren't you?''

　Lilith asks for confirmation, but I had no choice but to reply.

'If there was a creature that could survive that blow and stay safe, I'm screwed. I guess I'll just retreat quickly, marry Miss Julia and sacrifice another live girl.

　Lilith gives me a jittery look.

''..........''

　I thought that I had been joking, but I didn't correct myself.
　But I didn't correct myself, because I knew that the blow I'd just struck would definitely have an effect on the Seasurpent.
　I quickly said to Lilith.


'Go on!'


　That being said, Lilith hurriedly followed behind me.

''Anemone seems to have used up all of her spirit power with the blow she just delivered. We'll take it from here!''

　Lilith checked on Anemone, who was breathing on her shoulder.
I'm afraid so.
　I agreed.

　The two of us rode on the back of the swirling sea serpent and went straight up to the top of the serpent's head.

　Along the way, Lilith put more magic power into her magic-impregnated sword and rushed up, slicing through the scales of the Sea Serpent.

　The Great Sea Serpent's scales are being scraped off as it merges.
　A large amount of blood spurts out, staining the blue sea red with blood, but it still doesn't seem to have reached a fatal wound.
　But that was also a calculation.
　I didn't expect to be able to kill this monster with that much.

　When I see Lilith slicing through the Sea Serpent's scales behind me, I ignore her and run up to the Sea Serpent's head.

　I don't consume any extra magic power until I run up to the head.
　All I had to do was to build up the magic power contained within me to the limit and prepare for a desperate strike.
　When I arrived at the head of the serpent, I thrust my Ouroboros staff at it.
　It was for this moment that I was able to hold back without doing anything to the head.
　Just like in the previous life, most of the creatures in this other world also have a weakness in their heads.
　There are very few creatures that do not die from destroying their heads.
　The only creatures that do not have a weakness in their heads are insects and some undead.
　This sea serpent is no exception.
　I was sure of that, so I released all the magic I had left for this moment.
　I unleashed all the mana I had inside of me.


''Ultimate Thunderbolt (Tall Hammer).


　It's one of the forbidden spells, the highest level of lightning magic.

　Even I think it's easy for me to think of lightning magic for underwater creatures, but lightning magic can do a lot of damage to all kinds of creatures. And as long as they were under the sea, fire-based magic was pointless.

　There wasn't enough time to do something meaningless, and in fact, this magic should have been the most effective against this monster.

　In fact, after being hit by the [Ultimate Lightning] strike, the Sea Serpent stopped undulating and froze on the spot.
　The smell of burning filled the area.
　It was like a lie that he had been rampaging so wildly just a moment ago.
　Wouldn't he just sink to the bottom of the ocean and die?　
　I'm sure everyone thought so.
　As if to speak for it, Lilith ran up beside me and said

''Quicksilver. Ike-sama, I didn't think you'd be so easy to exterminate.

Easy?　If you think it's so easy to rain down cannons, summon spirit kings, and kill them by spraying them with forbidden magic, then I'll have to rewrite the lexicon of this world.

　--I stop the sarcasm right there.
　Because I can no longer afford to be sarcastic to Lilith.

I think it's time to rewrite the lexicon--or rather, the encyclopedia--of this world.

　And then I said.
'What you said. You said something so out of line it raised a flag.
　And then he spat out the words with even more acidity.

　A great shaking underfoot.

'Hey, what's this?'

　Lilith asks me.

　I reply.

'This great sea serpent is immortal. -- at least it seems that even a forbidden grade magic couldn't defeat it.

　As I continued, I still need to rewrite the entries in this world's dictionary, and the great sea serpent began to work again.

　The fact that it hadn't twitched a moment ago seemed to be a lie.
　The body of the giant sea serpent, which had been sinking, slowly rose up from the sea.
　Then, just as before, it undulated its huge body and began to rampage again.
　The giant sea serpent flails about, desperately trying to shake us off.
　It's probably not willing to take that blow again.

''You don't have to worry about that, that forbidden magic can only be struck once.

　I wanted to tell him that, but there was no way this great sea serpent would listen to me.
　There is no such intelligence.
　All we could do was to desperately hold on to the circular snake's staff that was thrust into the head of the giant sea serpent.
　Lilith also grabbed onto my waist and held on to me so that I wouldn't be shaken off.

''Ah, Master Ike, isn't this tasteless?　I thought you'd need to have Demon Lord level magic to kill it.　You can't fire a series of forbidden spells without at least wearing an immortal robe. Wouldn't it be better to pull back and regroup here?

　Lilith argues so desperately, clinging to me, but it might be the right way to think about it.
　At least that's what a decent thinking person would do.

　However, unfortunately, I, who is touted as 'the strongest magician in the Demon King's Army', didn't have any decent thoughts.

　I've been picked up by my demon grandfather and raised as a demon, so there is no way that this human being has any common sense at all.
　I'm going to give orders to Lilith.

I'm not going to be the only one who can do that. If we do this much damage, he may return to the dormant period. I don't want to move on the premise of 'maybe'.

　At least a lot of human lives were lost in this one battle.
　If we let this guy get away with it here, we won't know how to defend ourselves when we see them again after death.
　Besides, if I didn't finish him off here, many more lives might be lost.
　I really wanted to avoid that.
　To avoid that, I give orders to Lilith.

I have a plan that I've prepared for just such an occasion. Lilith, I'm sorry, but I'm going to head to Eltria and tell her that I'm going to activate Plan C.

Plan C?

　What's the plan?　Lilith doesn't ask, "What do you mean?
　She must have seen the seriousness in my face and sensed that I was in urgent need of help.
　Without a single word, she returned to the ship where Eltria was on board.
　I looked away from it and decided to endure it.
　I desperately clung to my staff and waited for the 'trump card' that Eltria would prepare for me to arrive.
　The Sea Serpent flails in a desperate attempt to shake me away from the forbidden magic that fed it.
　They swell and flail about.

　Occasionally it would sink to the bottom of the ocean and try to choke me out, but I would still hang on, and even with leverage, I couldn't get it out of its head.　

　I don't know if I've ever had to endure anything like this since I was trained in witchcraft by my grandfather when I was a child.
　Although he was a kind grandfather, he was a bit of a pain in the ass when it came to the practice of magic.

　There were times when he had to be hung upside down and dipped in water until he was on the verge of suffocation or thrown out into the snowfield in the extreme cold to open up the magic circuit (odo) inside him.

　I should be grateful that I am able to endure these hardships, but the hard work my grandpa gave me was duly rewarded.

　I had been biting at this monster for a dozen minutes when Lilith and Anemone returned with a large barrel.

　As soon as I saw this, I knew we were going to win.
　I shouted out, "Lilith and Anemone!


It's Lilith and Anemone!　We're going to drop that barrel into the ocean!


I understand!


　They both agreed at the same time and threw the barrel into the sea. I'm not going to be able to get a good look at it, but I'm going to be able to get a good look at it.

　Then I use the magical power I left behind to transfer onto the barrel.
　The Seerserpent stops moving for a moment because the obstructionist on my head has disappeared.
　However, he doesn't seem to have forgotten just the existence that persistently hurt him.
　Does he have some degree of intelligence, or is it his instincts as a beast?
　Just as I had imagined, he was coming towards me.
　I stare at the scene as I do.
　As it is, the Sea Serpent would swallow me up in one gulp, but that's fine with me.
　It's not that I've given up on life.
　Nor do I pretend to be the hero of a story about finding life in death.
　It's because I thought this was the best way to efficiently kill this monster.
　The Sea Serpent swallows me, who doesn't even twitch, without hesitation.
　He doesn't even know it's a suicide mission, but he swallows me whole.
　The area is enveloped in darkness.
　But my body is intact.
　It's even called a "sea snake".
　I'm sure this guy is some kind of snake, and he looks just like a snake.
　I knew it wouldn't be chewed, and I was right.
　I'm still alive and breathing even after being swallowed in one gulp.
　But when the powerful stomach acid-like substance fell on my clothes, my clothes melted in a flash.

The best dressmaker in Ivalice made this one for me,

　And I was sorry to Satie for ironing it so carefully.
　I let out a complaint and decided to retaliate against the monster for ruining this outfit.
I illuminated the inside of the monster's stomach with the magic of 《Lighting(Light)》 and made sure it was in place.
　Of course, that was the large barrel that Lilith and Anemone had brought with them.
　After confirming that there is a fuse attached to the top of that barrel, I looked at it and cast an "ignition" spell on it.
　The fuse lit by the magic of ignition, and the large barrel at the end of the fuse was naturally filled with explosives.
　And it wasn't just free explosives either.
　It was a powerful explosive specially formulated by the witch Sephiro.
　It was blended with spiritual and secret medicines imported from the elven forest, making it more powerful than ordinary explosives.
　What was even more egregious was the large amount of lead balls in the barrels.
　If it exploded, it would spread and cut through everything around it indiscriminately.
　Literally to shreds, miserably.
　If this quintessential guy was hit by that in his stomach, he would be done for.
　The moment the fire from the fuse ignited the gunpowder in the barrel, this guy would be dead.

　No creature in this world could survive having its scales torn to shreds by the Spirit King, having its head directly hit by a forbidden grade magic, and having its stomach crushed to a pulp.

　The only regret is that this guy's death was almost certain.
　I will not be able to witness the ripping apart of his innards.


Well, if I'm going to witness it, that means I'm going to blow myself up with him.


　When I finally blurted that out, I started chanting my magic.
　Of course, the magic I'm chanting is the Transmigration magic.
　I didn't want to have a heart attack with this monster.

　I escaped from the Sea Serpent's body just in time for the big barrel to explode, and I looked down from the air.


　I watched the moment of the Sea Serpent's death.


　The explosion wasn't very loud.
　It was only natural since it exploded in his belly.
　Also, the roar of death was gentle.
　The explosion of the large barrel of bombs must have killed his lungs at the same time.
　It seemed that it could no longer even raise its roar.
　The monster, which was called the "Great Sea Serpent," gave a final twitch and sank to the bottom of the sea.
　We had successfully defeated the legendary monster.
　When I witnessed this moment, I couldn't help but fall to my knees.
　For a moment, I feel faint.
　Lilith and Anemone rushed over to me to support me, and I managed to avoid falling into the sea.
　That's how much magic power I've consumed, that's why.
　Lilith looks at us with a rare look of concern on her face.

'Are you okay?　Master Ike.　

　That's an auspicious word for this guy.
　It must have been such a fierce battle.
　I said, forcing a smile so as not to worry him any more.

Don't look like that. Say it like you always do. The strongest sorcerer in the demon king's army can't lose,

　Did Lilith respond to my joke?
　Or was she being considerate?
　I don't know, but Lilith gave me her usual devilish smile.

''That's right. There's no way Ike-sama will lose. If you want, there are two or three more legendary-grade sea serpents out there, and he'll be able to defeat them all by himself.

　When I made sure she was back to her usual Lilith, I responded to her as usual.

''At least the next time we fight, we can ask for reinforcements from the Demon King's army commander class.

　And--.
