Bind 'em down, put on Gojou's school uniform (they're close to the same height, looks like), toss on a wig, maybe makeup and contacts. Quick and cheap. The rest is attitude.
He mentioned once that the school uniforms in the anime were similar to their own school's. Bet he tossed on some makeup and a wig for some sweet boy+girl cosplay.
@Kaarme That's a bit like chiding English speakers for not knowing every word in the language. Japanese has 46 hiragana, 46 katakana, and about 50,000 kanji characters (of which about 2,000 make up the basic set that allow people to call themselves 'literate'). So, yeah, learning how to read is...
"We are in our teens and SO in love and will never break up ever ever ever!"
:skip to second year in college:
"Oh her? Yeah, we haven't talked since high school. Dunno what that was all about anyway."
Judging by the way they talk about it, I don't know if she can ever officially "get married." Succession problems with children of former emperors and all that. But she and Misono are gonna be together and they're gonna be happy and that's just how it is.
I just hope they won't be traveling...
