[OOC] Memory issues!
Every time Yuuto uses one of his cards to transform into Kamen Rider Zeronos (which he won't have a reason to do unless he has to fight someone/an imagin shows up in the City), someone forgets about him. There are two kinds of cards, green and red.
★★★ The green cards activates the Altair Form, and uses up a memory of the older version of Sakurai Yuuto. (I'm guessing those cards won't be an issue here, since no one has met that version.) If Yuuto turns the card in the belt, he merges with his imagin Deneb (not important since Deneb isn't here, but throwing it out there just in case) and activates the Vega Form.
I don't know if I'll be using these cards at all in the game, seeing as Yuuto ran out of those in canon already. Probably not.
★★★ The red cards, on the other hand, activates a form called the Zero Form (very original, I know) and uses up people's memories of the young Yuuto, who I am playing. I'm thinking that every time I'm going to use one of those cards, I'll contact the player of a character who Yuuto has talked to (no matter how briefly) and ask them if they are okay with forgetting all about him.
I guess if someone really wants to remember him, we could always call on the City's ability to restore buildings and waking people from the dead after 24 hours?
