Binan Zaibatsu

Nanako Fujiwara, a socially isolated high school girl, remains an outcast even after transferring schools—until one day, her life takes a dramatic turn! She’s unexpectedly tasked with a crucial mission: selecting the next heir of a powerful conglomerate (zaibatsu). To "accurately evaluate the candidates’ leadership qualities," she must live with four dazzlingly handsome brothers competing for the title: Yamato Mitsurugi (Eldest): Flawless Student Council President Vibe: "Excellence isn’t my goal—it’s my default." Shizumaru Tenhou (Second): Undefeated Street Fighter Vibe: "Try saying no. I’ll make you regret it." Hikaru Sennen-zaka (Third): Illegally Adorable Mascot Vibe: "Nee-chan, let’s bake cookies!" (…Why is his stock portfolio outperforming Wall Street?) Ukyou Sumeragi (Youngest): Mysterious Beauty Incarnate Vibe: "You keep staring… Do I haunt your dreams?" The Catch: Each brother deploys every tactic imaginable—from sweet persuasion to corporate sabotage—to win Nanako’s favor. **Original Webtoon:** [JumpToon](https://jumptoon.com/series/JT00018/), [Cmoa](https://www.cmoa.jp/title/306934/)
