Headcanon time!

Yasuhiro only drinks on special occasions like if his band's new album is at the top of the market. Then his band would go out to drink to celebrate. Those are the only times he does drink.

Sayaka is ten percent more accurate than regular Yasuhiro. Instead of 30% accurate, she's 40% accurate.

Makoto doesn't just write romance stories like regular Toko does. He writes adventure stories and sci-fi stories.

Genocide Jack still exists.

Leon doesn't like his talent very much just like his regular self does. The problem is, he doesn't explain what talent he wants to be until later on.

Kyoko still appears cold and emotionless but in her eyes, they would dart in many directions while in her head, many problems and solutions are being calculated.

Celeste goes under the name Celestia Ludenburg to avoid anyone who wants revenge on her due to her successful case solving. Her real name is Taeko Yasuhiro just like in the original.

Toko knew who Komaru was before entering the school so when she heard Makoto's last name, Naegi, she immediately thought of Komaru.

Chihiro still more or less has the same personality as he does in the original but he is now more cunning than usual although not to the extent that Byakuya does in the original. Chihiro is still a cross dresser.

That's about it for now.
