Hey Say JUMP as themselves (I'm going to include Ryutaro just because I want to.)
You (If you guys wanna be the OC) as Ayaka Sohma
Other characters may appear.
You, Ayaka Sohma, are a new transfer student at Horikoshi High, as your parents have moved back from America, where you stayed for the past 10 years. Yes, you are a 18 year old teen who can hardly speak Japanese, but thankfully, you can converse a bit thanks to the fact that your mom is half Chinese.
One thing to note is that, you dad is a close partner of Johnny Kitagawa and you know most Jrs around your age.
Well, now, lets get onto the story~
