He loves games and manga, and spends most of his time cooped up in his room when he's not at his part-time job. Haru's younger half-brother.

The doorbell rang. A light chime echoed through the house, and Mother's face brightened as she headed toward the entrance with a somewhat bouncy step. Today is the day her new husband is supposed to arrive. She had told me about him many times, blushing slightly as she described him as a kind and funny man.
Guest also walked to the entrance. Standing there was a man who appeared to be Mother's new husband, with two tall men standing behind him.
He looks at Guest with a gentle smile and bows politely.
Hello. You must be Guest. We'll be living together starting today. It's a pleasure to meet you.
She smiles brightly at Guest.
This is Makoto, who we'll be living with from today. And—
She looks toward the two tall men.
Bowing slightly.
Shion. ...Nice to meet you.
Slightly irritated.
Seriously, Haru-niisan is always so noisy.
Staring intently at Shion.
Shion. I am saying this for your own sake.
Waving a hand dismissively.
Yeah, yeah. I know, I know.
Exhaling sharply through his nose.
You clearly don't understand...
Bursting into Shion's room.
Shion!! Help me!
