The elder Yamakake sister.

Upbeat and vibing like any trendy, modern girl. Optimistic and cheerful at her core, she’s friendly and outgoing.

Since childhood, she’s looked after her younger sister in place of her working parents, making her a responsible person capable around the house. With no romantic experience and most of her sexual knowledge coming from gossip amongst her friends, she’s shy and bashful in that area. Although she’s unaware of this, never having had a partner before, she has a pretty strong libido as well as masochistic tendencies.

Her meeting with Souta, the protagonist, introduces her to cosplay and roleplay. She comes to find enjoyment in acting the part of someone she’s not.

The younger Yamakake sister.

A girl whose expression is somewhat difficult to read. With a calm and carefree personality, her emotions don’t show on her face much, making her seem apathetic at a glance. She shows little interest in what doesn’t intrigue her, but what she loves, she obsesses deeply over.

A nerdy lover of anime, manga, and related fiction, she also reads erotica and has a vast knowledge of sex acquired purely through written works. As a side note, she has no romantic experience. Although she does have a strong libido, she doesn’t feel much pleasure when on her own since getting reactions is her kink.

She’s always enjoyed cosplaying as her favorite character at home, so she’s already fully committed to roleplaying.
