Kotetsu Faction

Led by Hyoudou Kotetsu, an old rival of Muramasa, his faction was the last one standing between Muramasa Ken Faction and Suzuran's Throne.

Their imminent fight didn't happen as Muramasa had to drop school after his mom got sick and Ken was expelled after almost killing a man for harrassing some girls.

Kotetsu was later defeated by a transfered student.
