Ikari

Ikari is boastful, aggressive and prone to schemes that vastly exceed the MK5's actual abilities.

He takes his leadership role seriously even though the gang rarely succeeds at anything it attempts. Ikari's confidence repeatedly survives humiliating defeats.

He can also be highly submissive around someone who intimidates him. During Miwa's leadership of the gang, Ikari becomes visibly frightened whenever he risks angering the self-proclaimed Queen.

Ikari is the quickest and most agile member of the MK5.

His speed allows him to appear suddenly when reporting information, but the series treats this more as an aspect of his movement than as a supernatural technique.

Even with the other MK5 members supporting him, Ikari remains far below Ishiyama's major fighters.

Ikari leads the MK5 through its recurring attempts to interfere with the conflicts surrounding Ishiyama's stronger students.

During Miwa's scheme, Ikari and his companions help attack Red Tail members and create the impression that Oga's group is responsible.

The MK5 later becomes a recurring comic faction, continuing to proclaim its strength despite accumulating defeat after defeat.

Shimamura, Nakata, Chatou and Buu are the four other members of the MK5 under Ikari's leadership.

Miwa temporarily commands the gang and frightens Ikari enough that even accidentally calling Aoi "Queen" earns him a beating.

Aoi Kunieda is targeted during the MK5's scheme with Miwa.

Good Night Shimokawa later associates himself with the MK5, although the five do not treat him as a true member.

Takayuki Furuichi later defeats the entire group and is consequently mistaken by them for a formidable master.
