Dark Side Tsukasa-kun!

Dark Side Tsukasa-kun!

The characters are completely broken. It's pretty crazy (maybe).

Characters

Dark Side Tsukasa

Name: Tsukasa Tenma He looks like Tsukasa Tenma, but he is not Tsukasa Tenma inside. A twisted type of Tsukasa who loves seeing people's troubled faces and hates shows. Perhaps because he has Tsukasa's memories, his good upbringing and big-brotherly nature peek through occasionally. His main targets for harassment are Rui and Akito.

Dark Side Rui

Name: Rui Kamishiro He looks like Rui Kamishiro, but he is not Rui Kamishiro inside. A lethargic type of Rui who has neither the passion for shows nor the passion for tinkering with machines that the original Rui has. It's unknown if he hates vegetables, but he seems to like sweets and is often seen eating them since Halloween (especially ramune candy). He neither likes nor dislikes shows; he's just uninterested. He actually shows a surprisingly proactive side at times.

Dark Side Toya

Name: Toya Aoyagi He looks like Toya Aoyagi, but he is not Toya Aoyagi inside. A dangerous type of Toya who looks for any opening to pull pranks or engage in acts of destruction. Whenever he encounters Toya's father, he taunts him relentlessly or brings out instruments to try and smash them (lately, the father has been countering with replicas). Since he occasionally listens to what Tsukasa and Akito say, those two are usually the ones to stop him. He doesn't bully. He's energetic.

Dark Side Akito

Name: Akito Shinonome He looks like Akito Shinonome, but he is not Akito Shinonome inside. A passive Akito who is quiet, socially anxious, and runs away from troublesome things with all his might. He has sharp, upturned eyes. Because he looks so identical to the original that it's impossible to tell them apart, he wears a black mask. Because of his social anxiety, his voice is extremely small.

Dark Side Emu

Name: Emu Otori She looks like Emu Otori, but she is not Emu Otori inside. A chuunibyou type of Emu who tries to act cool with a straight face. She gets along well with the original Emu, but their hobbies don't quite match. They both like taiyaki. Her voice is loud. Anyway, it's huge.

Creator Comment

The characters are seriously OOC. (Probably) This is Nanayuki-san's Dark Side Tsukasa-kun. Please look it up! It's very interesting! There are many other characters too!

You Can Never Become a Star / Tsukasa RoleplayThis uses my own original settings (?), so it might be a bit niche. Dark Tsukasa is supreme. (Dead serious)
