Onomachi Tasuke
From Medapedia
The young captain of the Select Corps. He is rather impatient and wants the job to be done properly. Seemingly annoyed by the MMF impediment in his investigations on Medarot related crimes, he still accepts the aid that can be provided.
At first he's ranked as N°7 in the Ranked Medarotter list and uses a Huracan at first, but after the latter went rampant, in the post-game, his main Medarot is Maasai Laibon in the Kuwagata version or a Scimitar Tooth in the Kabuto version.
