Kume has a noticeably short stature and a side-parted hair.
When marching against Yokohama's gray zones, Kume wears a white Bleach Japan T-shirt over a black, long-sleeved T-shirt, a pair of black pants, and a pair of black leather shoes. As a Kanagawa 2nd District candidate, he wears a black suit over white shirt and magenta or blue tie with a pair of black pants and black leather shoes.
A staunch believer in Bleach Japan's cause, he is willing to go to drastic measures to ensure that all of Japan's "grey zones" are eradicated. While he genuinely believes that Bleach Japan's actions are for the greater good, this has led to a black-and-white mindset, and he is described as a "dangerous person, who is not afraid to use violence."
He is aggressive in his speaking and extremely snarky, especially shown when he mocked Nonomiya's death while claiming that Otohime Land closed down thanks to "Bleach Japan's tireless efforts", and resorting to calling Kasuga and his party different names when called out.
Yakuza: Like a Dragon: 2000-2019
A branch manager of Bleach Japan, Kume has a blind faith of the organization and does not question Ryo Aoki's true intentions, or the purpose of the organization. His following of the group has led to run-ins with Ichiban and his party.
After learning of Aoki's true identity thanks to the video that Joon-gi Han leaks online, Kume suffers a psychotic breakdown as everything he knows is revealed to be a lie. He tracks Aoki and Ichiban to the coin lockers, and stabs Aoki just before he turns himself in. His whereabouts after the stabbing are unknown.
- Kume is the only boss to not be featured in the Sujidex.
- The seat Kume runs for, Kanagawa 2nd district, is held in real life by Yoshihide Suga, the Prime Minister of Japan (2020-), who has held the seat since it was created.
- The given height of 165 cm (5′ 5″) is based on the character model's scaling factor within the game's data. For Dragon Engine games, this method is believed to be very accurate (±1 cm). However, this is intended as an estimate, not a substitute for an official statistic.
