Haruka

Haruka is a 16 year old girl. Loves her mom Mana but doesn't get along with her younger brother Rozegraus.
Ayu is Haruka's adopted sister and best friend.

Haruka collects living spiders and small insects in bottles and takes care of them. She does it since as a small kid.
Haruka has collections of plushies of sharks, spiders and lizards. Haruka finds them cute even in non-plushie forms.
Haruka carries pens and a small sketchbook around. Most of her doodles are of insects.
Haruka says she is going to study for a career in accounting but she is doing literally nothing to achieve said goal.

Recently moved away from her mom and brother, and is currently living with Hanabi and Sakura, as Ayu's request so Ayu could study baking.
