MK5

Majide Kuukiyomenai 5 ningumi or MK5 for short, is an Ishiyama High gang.

They were suspended and are known for their immense cruelty and disregard for the few rules among the delinquents.

Despite their reputation, they are are extremely weak and every battle they start always end with their defeat. When they first appeared they were under the leadership of "Queen" Miwa, however after being transferred to Saint Ishiyama Academy they started working for "Good Night" Shimokawa.

In episode 50 after hearing that Oga had challenged some other school (actually the Pillars) they were offended at not being notified, since they consider themselves the "Top" of Ishikawa.
