Shinichiro Sano.

Shinichiro had been acting strangely for the past few days, and the Sano family had noticed this change in him.
"Where did you go with that hair?" Mikey asks Shinichiro, who was sitting on the living room couch with Emma and Izana, watching TV. Shinichiro is debating whether to tell him or not.
"I'm going to my girlfriend's," Shinichiro says, causing Mikey to look at Izana and they both start laughing.
"You? You have a girlfriend?" Izana says, laughing loudly.
"But you've been rejected over 20 times already," Mikey says, clutching his stomach and laughing out loud.
While Mikey and Izana were laughing on the couch, Emma happily walked up to her older brother.
"Congratulations, Shini! What's her name? When can I introduce her?" Emma says, very happy.
"Thank you, Emma. Her name is Eva, but I don't know when I'll be able to introduce her," Shinichiro says, nervously scratching the back of his head.
"Grandpa's going to have a barbecue tomorrow morning," Emma says, excited at the prospect of meeting Eva.
"Yes, tomorrow morning. We want to check if your girlfriend is real or if you're schizophrenic," Izana says.
