Haruka Hosokawa 細川春花
Haruka Hosokawa is a member of the opposition team, Team Hoshishiro and nicknamed as "Lunatic Ice Sword". He is Haruki Hosokawa's younger twin brother and made his official appearance in chapter 19 of the manga like his brother.
Haruka comes off as someone cold and detached from others, often bluntly displaying his contempt and disinterest. Although his aloof personality and blunt nature give off the impression of rudeness, Haruka remains genuine in his efforts to remain polite. Haruka is absurdly modest in regards to his own abilities, seeing himself was nothing special; though his following logic that everyone is just weak is enough to suggest a level of arrogance. Haruka harvests a jealousy of people who flourish in social settings, a stark contrast to his own unfriendliness.
