Yuuto is sent back to modern Japan, where he's forced to make a choice: stay there with his beloved Mitsuki, or go back to save everyone.
I couldn't think up a future 
where I was happy without you.
eine Zukunft, in der ich ohne dich glücklich bin,
scheint mir unmöglich.
no veo un futuro donde sea feliz sin ti.
no veo un futuro donde sea feliz sin ti.
je ne veux pas d’un avenir
sans toi.
non riesco a immaginare un futuro 
in cui sarei felice senza di te.
eu não conseguia imaginar
um futuro feliz sem você.
я не видела будущего, в котором 
счастлива без тебя.
