OVA
Description
Shuntaro Michikusa is a supporting character introduced in the second story arc of the original Agent Aika OVA series. He is a recent graduate of the salvager training school, having passed with barely acceptable grades. Through a family connection, he joins the K2 Corporation, where his father serves as the president of a major salvaging company.

Physically, Michikusa is a slender, tall, and handsome young man who can easily be mistaken for a model. He has short red hair and black eyes. His typical attire consists of a yellow shirt with a green tie and an asymmetrical grey jacket that has two pockets on one side and none on the other.

In terms of personality, Michikusa is feminine in mannerisms, somewhat airheaded, and frequently engages in crossdressing, including donning various uniforms of the Delmo Corps for undercover or comedic purposes. He is cheerful and well-meaning but often comes across as clumsy or scatterbrained. He uses a kappa puppet and an exaggerated squeaky voice in attempts to cheer up his teammate Rion Aida, though these efforts usually annoy her and result in him being hit.

Michikusa's primary motivation appears to be supporting his teammates and contributing in whatever non-combat way he can. He is the only member of Aika Sumeragi's group who never engages in combat at any point in the series. Instead, he cheers for Aika during her battles, carries heavy objects for the team, and provides moral support. His lack of combat ability is offset by his willingness to help in logistical or supportive roles.

His role in the story is that of a comic relief character and a non-combatant assistant. He is introduced as a new hire at K2 Corporation and becomes part of Aika's salvage team. While he does not participate directly in the action, he accompanies the group on missions and occasionally wears Delmo uniforms to blend in or for amusement.

Key relationships include his interactions with Rion Aida, whom he tries to befriend but who finds him irritating, and with Maypia Alexymetalia. It is hinted that Michikusa and Maypia are dating: he acknowledged meeting her before realizing she was an agent, and he deliberately chose a café as a meeting point to introduce her to the team. They are also seen wearing clothes with an identical color scheme, and Maypia blushes and appears confused when Michikusa puts on a Delmo Corps uniform.

Michikusa shows no notable development over the course of the series; his role remains consistent as a cheerful, non-combative supporter. He does not have any special abilities or combat skills, but his endearing and lighthearted presence provides contrast to the more serious action sequences.
