Sengoku Taiga♀

First cousin to Sengoku Ichiru, and an elementary student in Mihama Academy’s sapper school. Taiga’s always lived a pampered life, having grown up as heiress to the Sengoku estate. She’s a quick-witted and intelligent girl, as evidenced by the fact that she’s already passed her university entrance exams.

With all the expectations heaped on her, it’s only natural that Taiga should come across as a little arrogant. This is one of the reasons why she tends to keep her distance from other people - though she’s quite happy on her own. Rena calls her “The Milquik Master”, following a serendipitous encounter back when she first arrived at Mihama.

Taiga is intent on participating in activities that are usually closed to children of her stature; she cares little for age restrictions, nor other people’s opinions of her. Eventually her persistence pays off, when Haruto finally heeds her request to join Class A.
