Giboshi, Lemon

Lemon Giboshi is the younger sister of Matoi Giboshi. Kindergartener. She is a true child genius who likes historical things such as Mito Kōmon, shogi, ojarumaru and often speak like an elder person (but has a childish and naive side occasionally as well). She has an incredible sense of taste: She is already the primary food taster for Chou Kanda Sushi and is often relied on by local and often famous national traditional restaurants to taste food. She is unyielding, like her elder sister Matoi.

[Spoiler] She originally hated toast but later grew to like it. [/Spoiler]
