Two nobles, Regis and Seira, arrive at Ye Ran High School as part of their investigation into a series of incidents in Japan. Raizel and Frankenstein conceal their identities when they interact with the duo, but Regis and Seira realize that M-21 is a modified human and grow wary of him. Meanwhile, Tashiro is caught up in another fight with street punks on his way home from school...
Next time you decide to get revenge, 
come when I'm alone.
،عندما تقرّرون الانتقام المرّة القادمة
.تعالوا عندما أكون وحدي
Wenn dir wieder mal nach ’ner Revanche ist,
erwisch mich allein.
Para la próxima,
búsquenme cuando esté solo.
La próxima vez,
buscadme cuando esté solo.
La prochaine fois,
venez quand je suis seul.
La prossima volta che volete provare a vendicarvi,
Na próxima vez que quiser se vingar,
faça quando eu estiver sozinho.
Если хотите ещё подраться,
приходите, когда я один.
