h4. Synopsis
[[Alisa Mikhailovna Kujou]] is a half-Russian, half-Japanese high school student who attends one of Japan's best institutions, Seiren Private Academy. With her unparalleled looks and silky silver hair, she can make anyone turn around if she walks past them. Her elegant persona, alongside intelligence, has made her the idol of her school.

On the other hand, Alisa's benchmate [[Kuze Masachika]] is an unmotivated student who sleeps in classes and always plays gacha games. Unable to be honest, Alisa sometimes expresses her thoughts in Russian so that Masachika won't understand. However, unbeknownst to her, Masachika understands Russian as well at the native level.
