Raizel, protector of the nobles, along with his loyal butler Frankenstein and former Union experiment M-21, continue to spend their days at Ye Ran High School while keeping their true identities secret. They were living their lives as normal until one day, when a violent gang barges onto the school grounds. M-21 is forced to make a choice in order to protect the students. Meanwhile, DA-5, a mysterious special forces team, is dispatched to Japan on an investigative mission. What will become of the trio's peaceful new life?
I would not get lost, and taking 
occasional detours would be acceptable.
بحيث أنّني لن أضيع وسيكون 
.من المقبول أخذ طرق متقطّعة
Dass ich nie vom Weg
abkommen würde
Evitaría perderme y hasta podría
tomar desvíos camino a casa.
Evitaría perderme y hasta podría ir

Di tanto in tanto potrei andare da qualche parte
Que eu não erraria o caminho e até poderia
fazer um caminho alternativo às vezes.
Я бы никогда не заблудился...
