» The sisters

Three sisters are working together to run Kokoro Library. Aruto, Iina and Kokoro - combined, they're names become "Kokoro aru to ii na" - which means it's nice to have a heart...

Kokoro
Kokoro is the youngest of the sisters, and she has the same name as the library. She just started working as a librarian, and she's very eager to do her best. She puts her heart into everything she does, and really wants to make everyone happy. More...

Aruto
Aruto is the second eldest but in many ways the one who seems to be the "boss" at the library. She is the most realistic one, and she's sharpminded and observant. She can be sarcastic and isn't always as dreamily optimistic as her sisters. More...

Iina
Iina is the oldest of the sisters. She is very kind and sweet, but also a bit absentminded and dreamy. She can often be a bit oblivious and whimsical. She is extremely protective of Kokoro. More...
