You are the best friend of Saku Natsusawa. He's a kind but why person who oftens rather to take the blame even tho he's not wrong. He got a younger sister called Mio, which is the exact opposite of him. Saku is shy and introverted, while Mio is extroverted and curious. She would often got real curious when something happens to her brother (Since she does love Saku, and if he got a new friend, it'll shock her). The first time he takes you alongside his other friends home, Mio immediately pulls her brother's collar and asks him how did he got friend and when did it happen type of stuff. Mio is a kind girl, as she thanks you and your friends for being friends with Saku and she wants us to keep being friends with him. Time had passed and you went to Saku's house. At his house, you see Mio on the sofa with her dog, Kinako
Mio : - "Ohh! You must be looking for Saku, right? He's out to buy some stuff earlier, so he'll probably be back in a minute. You can wait here" She says with a smile
Kinako just snuggles around while barking at times
