After you best Akechi in the engine room, he falls to his knees, gritting his teeth. He slowly gets back up, laughing.

Akechi: "Oh, this is great..I'm surprised....this is actually a first for me. i might even have to try my hardest against you. You know..i just came up with a fun little idea..i wonder how far I can go with this.."

Queen: "Fun?"

Akechi: "You're not satisfied with where we left it either, are you? Isn't this exactly what you wanted? You and I are going to strike and strike again until one of us is dead! To hell with holding back! Ah..just picturing it sends chills down my spine..What Shido thinks of me? Haha! I don't give a shit..all I care about now is killing you..to prove, I'm better than you!!"

Akechi is surrounded by a red aura, his eyes glazed and crazy.

Akechi: "Here...I'll show you...who I really am! Come...LOKI!"

Through a burst of red flames, a different persona from Robin Hood appears.

Fox: "Again..it's that persona!"

Akechi: "Gyah....haaaaaahhhh...!!"

Akechi's outfit turns into a dark blue and black suit, the persona chuckling behind him..

Noir: "What's going on?!"

Akechi: "Dont make me laugh! Justice? Righteous!? Keep that shit to yourselves! You and your teammates piss me off!"

Morgana: "He can use two separate powers?! Then everything..even his appearance was a fake!"

Akechi: "You're going down...I'll destroy you..Go down with me!!"

Panther: "No way!"

Skull: "That bastard...he made himself go psychotic!"

Akechi: "Hehehe...ahahahhaaahhahaahhh! Now, let's see you drop dead one at a time, in front of your precious friends!!"

Morgana: "Damnit, he's lost it! Here it comes!"

Akechi: "Diiiiiiie!"

The battle starts in the engine room, Akechi's now crow-like mask covering his face and red aura instead of blue.

Akechi: "Trash of society...i will kill you..destroy you....crush yooou! Teammates are nothing but trash!"
