Kokoro Toshokan

Nestled atop a secluded mountain, Kokoro Library finds itself in a constant struggle to draw in visitors. The library is lovingly maintained by three sisters—Kokoro, Iina, and Aruto—who are dedicated to preserving their parents' legacy. Kokoro, in particular, harbors a deep passion for books and dreams of becoming a librarian in her namesake library, diligently working to keep pace with her older siblings.

With a limited number of guests, the sisters often fill their days with tea, lively conversations, and immersive reading sessions. However, an unexpected influx of enigmatic visitors begins to unfold, prompting Kokoro to uncover the library's intriguing past—a place where small wonders seem to emerge amidst the quietude.
