He grins at the correct assumption, although it falters a little at the mention of Asuma. "I am! Hinata graduated the Academy with my team, so we grew up with her too." He frowns. Anyone else from his world going home, Chouji could accept. Asuma and Neji are the hardest because he knows what's waiting for them there. "Asuma-sensei is no longer in Luceti, though." No longer anywhere, if he's not here. Familiarity with Japanese will probably give Luke at least a tiny bit of an idea how important Asuma was to Chouji.

Chouji nods. "So you kept your full name, and the rest of us borrowed part of it." He still feels caught between the two names, memories jumbled enough that neither one is entirely his, because both are.
