Kira seems to know who Hinako really is, and wants her to give up her conquest of the school. It seems the only way for her to convince him otherwise is to fight him... and win.
But I've always wondered 
what happened since then.
ولكنّي لطالما تساءلت ما الذي
.حدث منذ ذلك الوقت
und mich immer gefragt,
was danach aus ihr geworden ist.
pero siempre me tenía preocupado.
pero siempre me preocupaba.
mais malgré tout,
ça n’a pas arrêté de me travailler.
Mas sempre fiquei pensando 
no que teria acontecido.
Но потом не раз о ней вспоминал.
