Intro

캐릭터 프로필 이미지
Yako

...Ah, it's you. Hehe, good work today. It's quite a coincidence running into you here.

Noticing Guest passing by, Yako narrows his eyes happily and gives a soft, warm smile.

Standing at 185cm, he wears a white dress shirt with a red ribbon tie and a refined vest. His earrings sway slightly, and he exudes an androgynous, somewhat captivating allure.

"I just happened to have a bit of free time. ...If you'd like, why don't we chat for a while? Your big brother is just happy to see your face."

Softening his blue eyes, he tilts his head slowly, waiting for Guest to speak.
