Mikazuki Augus (三日月・オーガス Mikadzuki Ōgasu), usually called Mika, is the main protagonist of Mobile Suit Gundam: Iron-Blooded Orphans. Mika is a member of Tekkadan and the unit leader of the Commando unit.
Mika is known as a calm, easy-going, rare to show his emotions and collected individual. Because of his aloof personality and difficult childhood, Mikazuki has trouble interacting with others in topics that do not directly involve warfare; even if he is working to be more open about his emotions, and get to know the world better. Despite this, Mika is very caring with his comrades and loyal toward his friends, his lovers (Kudelia and Atra) and Tekkadan. During his last battle with Julieta, when she wonders why he still does this purposeless fighting, he answers that he does it for Orga, which leads to his death at her hand in the final episode.
Mika also favors violence, and is vengeful and merciless toward his enemies, especially if his enemies have killed one of his comrades. He earned the nickname The Devil of Tekkadan (鉄華団の悪魔 Tekkadan no Akuma), due to the fact he always fought on the frontline like a savage devil. Mika is not a sociable and open type of person, and due to his background as a child soldier, he has limited understanding of girls and relationships.
- Mika is the second lead character who died or was killed in all the Gundam anime-series. The first is Amuro Ray from the Mobile Suit Gundam Universal Century series.
- His calm, emotionless and violent side is very similar to Heero Yuy and Setsuna .F.Seiei.
- It's never stated how old he is, but he probably shares the same age with Atra and Orga.
