The underwater labyrinth had become a den of ruby golems.

　A magic power denser than on earth.
　There were no people - that is, no natural enemies.
　They had been in such an environment for many years.
　It could be said that it was inevitable that they multiplied.

''Hiiiiiiiiiiiiiiiii!

　A pathetic scream.
　It wasn't a student, nor was it a civilian.
　It was a magical unit of the Saw merchant nation.

　A ruby golem attacked one of the troops.
　The one who sashayed there was a girl.

''Haaaaaaah!

　It was Mucha who spat out the spirit of the cleaver.
　He shoots a fist strike towards the Ruby Golem.
　The demonic beast's physique is larger than Mucha's.
　As the name "Ruby" suggests, its surface layer is quite hard.

　In contrast, the fist strike fired by Mucha is an unenhanced bare hand.
　The fist was small, and it seemed a little unreliable to shake the physique of the ruby golem.

　But--.

　Gun!

　Mucha's fist strike hit the Ruby Golem.
　When it hit the part of the body that hits the temple in humans, the body of the ruby golem staggered.

''-----!

　One of the magic squad members was surprised.
　The members of the magic squad who were watching nearby were also exclaiming with their mouths wide open.

　Unfortunately, they must have noticed the awfulness of Mucha's fist strike, even if they didn't come close to overthrowing it.

　I was watching from a place where I had pulled back a bit, and I put my hand on my chin.

''As expected of a witch, I suppose.

　The sturdiness of their bodies and the suppleness of their muscles.
　The high level of basic ability is overwhelmingly higher for a magician than for an ordinary human.
　Although Mucha's body looks slender, it is far more efficient than those in the magical unit.

　Even though the magical unit is surprised and I admire them, Mucha is not careless.
　His purple eyes flashed even in the bright undersea labyrinth, which was particularly strong.

　I turn to the Ruby Golem, who is trying to get into position.

　At that moment, a voice was heard behind Mucha.

''Mucha-san, take five steps back!　The enemy's counterattack is coming!

　It was Sarasa's voice.
　Its eyes were glowing vaguely.
　It is activating 【Future Vision】.

　Sarasa's tactical reading has already reached the realm of 【Future Vision】.

　However, there was a reason why she was activating it like this now.
　It's because people's readings are incomprehensible against demonic beasts.
　Especially against a hexenbiest that you have never seen before, as long as you don't know their abilities, it is dangerous to use a human's reading.

　In that respect, 【Future Vision】 is a magic that has more analysis ability than human thoughts.

　In an instant, it is able to see through its characteristics and predict the future (ahead) of its movements, whether it is the first time seeing it or a monster beast, and show it to the magician.

　Mucha obeys Sarasa's words quietly.
　He jumps up in a big way and takes 5 steps back.
　In the place where Mucha was, two ruby golems have fallen.

　A total of three of them.
　Hmm....with S-ranked demonic beasts, it's going to be tough for two of them to take care of themselves.

　I'm thinking of a helper.
　However, neither Mucha nor Sarasa asked me for help.
　They don't seem to have any intention of retreating.

　Sarasa quickly activated her magic.

　[Magical beast scanning]

　It's a magic that captures the physical characteristics of a demonic beast and analyzes the weakest part of its structure.

　In an instant, Sarasa discovered the Ruby Golem's weaknesses.
　Without a moment's pause, she drew her bowstring.

　Seeing this, the magic unit buzzes.

''Na!　A bow?
There's no way an arrow could enter that hard surface...

'Shh!　Please shut up.

　Sarasa didn't put the bow down.
　Rather, she focused more deeply.
　There were three arrows that were nocked.
　He released them all at once.

　The three arrows cut through the air.

　They pierced the hard ruby golem's outer skin.

Oh!
'There's an arrow in the golem's skin...'
What kind of a strong bow?

　The magic squad is surprised.

　It's not that Sarasa's bow is strong.
　It's just that that part was soft based on the analysis of the [Demon Beast Scanning].

　Ore-based demonic beasts like ruby golems have a weak part in their body somewhere.
　When ores crystallize, impurities inevitably enter their bodies.
　Those impurities would get into the gaps between the crystals, creating a fragile part of the body.

　Sarasa had discovered that weakness in the 【Magic Beast Scan】.
　However, the fact that she was able to accurately hit that area with an arrow was the result of training that the members of the magic squad beside her could not even imagine.

''As I thought, you've gotten stronger, Sarasa.

　I narrow my eyes.

　Sarasa, on the other hand, was only concentrating on the battle.

''Mucha-san!　Attack that arrow part!

I understand.

　Mucha, who had retreated once to watch the situation, started running again.
　He pulled out the shortsword that was stuck in his waistband and released it.

　Naturally, Sarasa's arrows wouldn't frighten the Ruby Golem.
　It attacked Mucha with arrows stuck in various places.

　Mucha activated the 【Searcher (Seeker)】 magic.

　[Double Body]

　Mucha's figure becomes two.
　It's a magic that disperses the presence.
　The ruby golem is easily trapped.
　It was the shadow.

　The ruby golem cuts through the shadow.
　But the real Mucha was behind it.

''First one!''

　Mucha poked his shortsword.
　He slipped the blade into the mark of the arrow that Sarasa had attached to it.

　The unstrengthened shortsword pierced the hard ruby golem's surface skin.
　The blade slipped further in and pierced the core of the ruby golem.
　It immediately collapsed.
　It was reduced to a mere lump of rubies.

　Two left.

　The ruby golem turned around and attacked Mucha.
　For an ore based demonic beast, its movements were fast.
　However, Mucha easily ducked.

　I activated the magic of 【Searcher (Seeker)】 again.

　[Silence]

　As the name suggests, it's a muffler.

You're awake.

　I grin.

　The Ruby Golem has no eyes or ears.
　It has no eyes or ears, nor is there anything in sight that could serve as an alternative function.
　What it does have is a lump of ore.

　If so, the lump of ore is probably what is used to determine the location of the enemy.

　It can be thought of as "sound".
　More specifically, it is the amplitude of air.
　By receiving that amplitude with the entire epidermis, the enemy must be perceiving something that is moving.

　Musha probably noticed this during the two rounds of battling.

　In fact, the movement of the ruby golem slows down.

　[Silence] muffles every human sound.
　Not to mention the sound of footsteps, the creaking of muscles and bones, even the sound of the heart, it's a magic that suppresses the amplitude of the air through magic power.

''The second one!

　Mucha stabbed his short sword into the ruby golem in the same manner as before.

　He turned and pounced on the third one.

''This is the end!

　He stabbed into the markings of the arrows that Sarasa had put on them.
　The ruby golem was torn down.

'Oh!'
S-ranked hexenbiest.
The students!

　The magic squad can only be surprised.

　I smiled, too.

　Brilliant, both of them.
　Probably the first time they combined the combination.
　In addition, it's commendable that two people who don't have the breakthrough power of Rowan and Cecil were able to defeat an S-ranked Ruby Golem.

　It should also be a good source of material in the expected demon battle in the future.

'You did it!　Mr. Mucha.

　Sarasa raises one hand.
　She tried to high five it.
　But Mucha did not raise her hand.
　She stared at Sarasa.

''The........Sarasa-senpai.......''

What's going on?

''It's not polite to call my seniors like this too much, but Musha-san (sic)....... Sarasa-senpai is my senior, so you can call me by my name.

　It was a point that was typical of Musha, who was very tight.

　Then, Sarasa gives a big smile.

'Then call me Sarasa.

That's not...

'I think there's something strange about me calling out to Mr. Mucha and Mr. Mucha not calling out to me.

'It's not that strange......... I'm a junior, and besides, I'm not a....

I don't mind that at all. Because Mucha-chan (I want you to know that she's my little junior, and she's my friend to fight with.

Cha-chan!

No?

　Sarasa lowered her raised hand and grabbed Musha's hand.

　Then Mucha said, "Bon! And then he makes a noise and turns red.

'Wow, okay.

Yeah. That's fine.

　Sarasa let go of Musha's hand, as her opponent wished.

　Then she raised it again.
　Seeing that hand, Mucha also raises his hand.

　Snap!

　A pleasant high-five echoed in the undersea labyrinth.

　I, on the other hand, peered into the depths of the labyrinth.
　I put my hand to my chin and think.

　It's strange.........

　Three ruby golems solidified and came out.
　Their movements were more like they were running away from something rather than attacking us who had invaded the underwater labyrinth.

''Hm........''

　I raise the corners of my mouth.

　Apparently, there are still some interesting things in the depths of the undersea labyrinth.
