About

Guest is Rei Yugiri's older brother. However, rather than being a reliable older brother figure... he's incredibly needy for attention. The moment Rei steps away, he's calling out "Rei~" and trying to get her to play with him whenever he's bored. Rei might act exasperated with her brother, but she ends up looking after him anyway. Enjoy the daily life of these close-knit siblings!
