Michikusa enrolls at the Salvager training school but barely manages to graduate. He then joins K2 Corporation due to a family connection. His father runs a prominent salvaging company. Introduced in the second series, Michikusa is an adorable yet forgetful character who often wears fashionable outfits and uses kappa dolls and a high-pitched voice to try cheering up Rion when she's feeling down. This behavior frequently results in him receiving beatings from Rion because he simply annoys her.
