Masuta Kira

Masutā Kirā, spelt in-game as Masuta Kira and often shortened just to Kira, is a member of the Shinsengumi. Because of this, it can be deduced that he possesses a Stand, though it is not currently known what this is.

Biography
Kira is hotheaded and ambitious. He constantly seeks to prove himself to Sefer Yetzirah by volunteering for the most dangerous tasks and missions, as well as showing off in battle. He carries six Katana, a testament to his love of flair, and practices tricks with them to use as taunts. Lucy Farr suspects he has a crush on Sefer, which he outright denies. His youthful nature is highlighted by his immaturity, and next to cool-headed Shinsengumi such as Original Zero, he appears as nothing more than a punk.

Negotiations with the Sahagin
Kira was introduced as the Kusanagi headed to the Sahagin homeworld of Saspa to attempt to gain allies. He walked with Lucy to the bridge, having waited outside the observation deck to boast that he had been assigned to Sefer's personal security detail for the upcoming mission. He then headed off to the throne room with Sefer to await delegates from the Sahagin.

Trivia

 * Masuta Kira's name uses the Japanese naming convention, where the first name is the surname, and the last name is the given name. He shares this distinction with Original Zero.
