Two years ago, Mikey learns that Kazutora is beefing with the motorcycle gang, the Black Dragons, and decides he'd fight them as well. But he wanted a valid sense of purpose to take on a motorcycle gang. Baji then suggests they make their own motorcycle gang. They want to create a gang where they can all put their lives down on the line for each other. Baji had been fighting all alone to protect the promise they made the day they created their gang and put their money together to buy a traffic safety charm.
I'm betting 100 yen that he was being used 
as an errand boy and stopped coming to school.
أراهن بمئة ينّ أنّه كان ساعيًا لأحد 
.ما فتوقف عن المجيء للمدرسة
100 Yen, dass er schikaniert wurde
und sich nicht mehr zur Schule traute!
Apuesto 100 yenes a que lo usaban
como chico de los mandados.
100 yenes a que lo usaban
como chico de los recados.
Je parie qu’il a arrêté les cours
parce qu’on le harcelait.
Scommetto 100 yen che lo usavano
come galoppino e ha smesso di venire a scuola.
Aposto 100 ienes que usaram ele como
garoto de recados e ele deixou de vir à aula!
Сто иен на то, что его
 шпыняли все подряд!
