ペンギン☆ブラザーズ

Hina Mishima transfers to Tokiwa Academy, a large private high school where students are divided into two feuding factions: those wearing white uniforms, led by the charismatic Shirayuki, and those in black, headed by the intense Nishizaki. As a new student, Hina joins the minority group of private-clothing wearers, called Greys, who are targeted by both factions. She navigates the school’s tense atmosphere, forming alliances with peers like the enigmatic Isshiki, a key figure in the white faction. Hina’s determination to challenge the factional conflicts draws her into confrontations and strategic maneuvers. Set in the sprawling campus of Tokiwa Academy, her actions spark new dynamics among the students. (Unreviewed summary by Grok 3)
