I used 【Legendification (Legendary Mode)】.

　This skill doesn't cause any visible changes from the surroundings when I use it.

　As the user, I felt the effects of this skill the moment I used it.

　Anyway, a tremendous amount of power came up.

　I don't need to look at my status to know that I was far more enhanced.

　If it were me now, I might be able to move at a speed where I can't react to his shield.

　Okay, let's do it.

　I raise my sword and begin to move as fast as I can.

　I was able to move at a speed that was previously impossible.

　I start off facing Oshima from the front, and as soon as I get close enough, I change directions and get behind Oshima.

　I slashed at Oshima with my sword.

　The shield is super responsive, but as expected, it doesn't seem to be able to keep up with my speed in this state.

　The sword hit Oshima's shoulder.

''Ugh!''

　It was still a sturdy one, and for a guy who slashed with pretty much all his might, the attack didn't seem to be that effective. It's not like he's bleeding from a cut. I appraised it and looked at its HP, but it still hasn't decreased that much.

　Maybe attacking with skills instead of attacking with a sword would be more effective. I get in until the attack is in time to hit it, and release 【Dark Blast】.

''Guaaaah!

　It hits the face, and it seems to be more effective than the sword shot I just used. Dark Blast] has spent a lot of skill points and raised its skill level to 7. The HP was reduced by about 150.

　Fortunately, Oshima doesn't seem to have the 【Regeneration (Regeneration)】 that Takei had. The damage is not automatically recovered.

　Sun's ability had a time limit, but... well, his has one. And if it wasn't, he'd be using it all the time.

　Since this is the first time I've used this skill by myself, I didn't know about the existence of a time limit.

'Hm, my shield doesn't have a time limit. It's just that shields look lame, so I don't usually take them out, and it doesn't matter if I keep them out all the time. If I can keep it out until your skills wear off, I win. You have no way of attacking me, you know.

　Indeed, if the [Legendary Mode] runs out, it's difficult to hit an attack.
　However, my opponent is also at the level of being unable to attack me as a bare minimum, so I don't think it's a win. Well, as soon as the goal of defeating Oshima becomes unattainable, I've practically lost.

　It's unclear how long the time limit is, but we have to defeat him before the effect of the skill wears off.

'Nya, I'm back!'
Tetsuya, you take care of the rest.

　Raina and Mek are back to their original form. They are no longer in a state where they can't fight. I have to take them down by myself.

　I then attacked them many times.

　The chances of the attacks passing were not 100%, and sometimes they were blocked by Oshima's shields. Naturally, if that happened, I would have to take the 【Dark Blast】 with my own body. Even though his defense power has been increased by Legendary Mode, he still takes quite a bit of damage.

　However, there were more situations where the attack came into Oshima.

''........Ku, shit.''

　After ten or so attacks, his HP is only a little left.
　The 【Legendification (Legendary Mode)】 is still going on.

　I'll decide on this one.

　I move at full speed and get behind Oshima.

　I'm faster than the enemy's reaction.

　I slammed 【Dark Blast】 into Oshima's face.

''Gu........ha.......''

　Oshima's HP dropped to zero and he collapsed on the spot.
