❣ Characters ❣

▲Mikazuki Enomoto

CV：Popura Sawano

Height: 156cm　Birthday: March 12　Blood Type: AB

The protagonist’s cousin, a freshman university student. She moved in because the house is close to campus.

Energetic yet sometimes clumsy. Her special skill is being immune to Mitsuki’s sharp tongue.

▲Mitsuki Hagiwara

CV: Kaede Akino

Height: 152cm　Birthday: December 24　Blood Type: O

The protagonist’s younger sister, an honor student at Hokuka Girls’ Academy.

She moved in with her brother because it’s close to school.

Introverted and poor at expressing emotions, yet sharp-tongued is her specialty.

▲Ryoko Ando

CV: Suika Suika

Height: 162cm　Birthday: August 12　Blood Type: B

A junior from the protagonist’s university, who became tied to him through a certain event.

After graduation, she joined the same company where he works.

Always acting like the “junior,” she’s proactive but can’t take the decisive step forward.

Her specialty is causing trouble for the protagonist, and she hates overtime the most.

▲Yoko Ando

CV: Shiki Asagi

Height: 150cm　Birthday: October 15　Blood Type: A

Ryoko’s younger sister and Mitsuki’s classmate.

A bright and energetic girl, though sometimes just as careless as her older sister.

Her biggest concern is that her height hasn’t grown at all since her first year of junior high.
