Berserk Button: While Kubota maintains a stoic attitude no matter what he is feeling, but harm Tokito in any way, he will show no mercy shown especially when he kills his old yakuza underlings and friends when Tokito gets kidnapped by them.
Gangsta Style: That or a crippling firearm-specific wrist deformity.
Over-the-Shoulder Carry: Carries Tokito like this when he first brings him to his apartment in chapter 26.
Parental Neglect: The implied reason for his social detachment. The Heroic Bastard of a Mysterious Parent, he was ignored by the people who raised him and scarcely less so by Kasai, who became his guardian after the death of his mother.
Evil Hand: His bestial right hand is a symptom of usually fatal W.A. use. The hand is abnormallystrong, but causes him fits of extreme pain, and the affected area is growing.
Morality Pet: Kubota's yardstick of good and bad is, essentially, what is good or bad for Tokito.
Older Than They Look: Tokito looks to be about 16 and physically appears younger than Kubota, he is actually three years older than Kubota, at the age of 20.
Tsundere: Both types, he's very affectionate and close to Kubota, but shows discomfort when someone suggests they are lovers, but also he can be short-tempered towards Kubota, but doesn't like it when someone makes advances towards him, bordering on Crazy Jealous Guy.
Dirty Cop: Makoto states that his uncle Kasai is "probably the most crooked detective in all of Japan." It's unclear how true this is, as Kasai hasn't yet been seen doing anything to earn him this distinction besides giving his nephew information on cases of interest.
Kasai: Listen, boys. I don't actually give a fuck who did it.
First-Name Basis: The only character who addresses Kubota as Makoto.
Friend on the Force: A good source of cover-ups, access to crime scenes, and official research on W.A.; he and Araki sometimes act as Mr. Exposition for the latter.
