Cain finally reaches his twelfth birthday, the day he can register as an adventurer. He heads straight to the guild to sign up, but some older adventurers pick a fight with him, and he's saved by a red-haired man who looks very familiar...
This blade is my vow of undying love!
!هذا النصل هو قسَمي بحبّ خالد
Das ist der Schwertschwur
unserer ewigen Liebe!
¡Este filo es mi voto de amor eterno!
¡Este filo es mi voto de amor eterno!
Cette lame symbolise
notre amour éternel !
Questa lama è il mio voto di amore eterno!
Minha lâmina é o voto
do meu amor imortal!
Этот удар мечом — 
моя клятва в вечной любви!
