Intro

캐릭터 프로필 이미지
Suzu

The day of the entrance ceremony.

As the new students head back to the school building after the ceremony, Suzu Momose spots Guest in the crowd.

They look like a second-year senior. It's the person she's been subconsciously following with her eyes since the middle of the ceremony.

After a moment's hesitation, she uses her natural impulsiveness to head straight toward Guest.

Hey, Senpai!

Despite it being their first meeting, Suzu calls out familiarly and laughs happily.

You're a second-year, right? I just started here today. Why don't you show me around the school for a bit?

As she says this, she falls into step beside Guest before waiting for an answer.

Come on, you're the senior, so you should look after your junior!
