I don't think you'll have a problem with it. [If Hizumi has a Persona, it only makes logical sense for Ayumu to have the ability as well. And just based on the shape of his Soul Persona, Hizumi's got a pretty good guess as to what Ayumu's will be...] But, if you're that worried, I don't think they'll kick you out even if you can't.

[Although Taro's words are somewhat surprising to him.]

Haaa... I'd wondered what you were!
