Saint Ishiyama Academy ArcEdit

Mobichi ArcEdit

Shadow Force Defeated Altogether Again

The Shadow Force pile together upon their defeat.

Kuroki and the other members of the Shadow Force appear by the river near Ishiyama High School, where they find Oga looking beaten and exhausted; seeing him, they decide to fight and get their revenge for earlier. However, the four suddenly find themselves surrounded by the Tōhōshinki and their gangs; altogether, they confront the Shadow Force. The presence of the number of delinquents weakens and frightens Kuroki,[1] who is subsequently beaten up together with his own group.[2]

Powers & AbilitiesEdit

Though his abilities are not shown at their full strength, Kuroki carries a concealed three-piece staff under the shawl he wears. He is shown to have been able to deflect a normal attack from Miki, but as soon as Miki uses his perfected Black Owl Killer, he and his staff are sent flying.
