The Sisters and the North Star

Himi Hoshino is an earnest middle school student who strives to fit in with her classmates by maintaining a polite, agreeable presence. One day, her peaceful domestic environment is completely transformed when her mother remarries. She gains a new step-sister, Subaru, who happens to be a remarkably quiet girl from her same school.

At school, Subaru is perceived as cold and distant, maintaining her privacy and keeping everyone at a distance. However, at home under the same roof, Himi slowly begins to see Subaru's sensitive nature and the emotional burdens she carries. The two girls decide to keep their new step-sister relationship secret from their classmates to avoid unnecessary gossip.

As they navigate middle school friendships, family adjustments, and individual self-doubt, their secret bond gradually deepens into genuine trust. Subaru helps Himi find the courage to express her true thoughts, while Himi offers Subaru a safe haven of unconditional warmth. Like the Polaris star in the night sky, each sister becomes an indispensable beacon for the other.

Written and illustrated by Mizuka Yuzuhara, this serialized work in Ribon magazine is praised for its emotional maturity and delicate touch.
