In order to prove that he is a true hero who has been summoned by a goddess, Schwartz, a high school student who is from Japan just like Tachibana and Jinguuji, has takes on a mission to defeat the living armor which has been attacking tradesmen near the Mercs territory. The living armor only targets magic items, and tries to take Schwartz's holy sword, Gram, and Tachibana's tiara, but...!
To think I've stolen a 
young man's first love...
...من كان يعتقد أنني قد أسرق الحبّ الأول لشاب
Ich war die erste große Liebe
von ’nem jungen Kerlchen wie ihm?
Y pensar que sería
el primer amor de un jovencito…
He acabado siendo
el primer amor de un chavalín…
Qui aurait cru que je serais
le premier amour d’un lycéen.
Se penso che ho rubato
il primo amore di un giovane uomo...
Acabei sendo o primeiro
amor de um jovem...
Эх, похитил я сердечко
совсем ещё юноши!
