“Um.” Michiko blushes. She is not prepared for this question.
“Uh.” Mizurou struggles to hide a laugh. “Why don’t you ask Uncle Hanbee.”
“Oh…okay.” Mizuki totters away to the living room.
“Three…two…one…” Mizurou narrates.
They hear a scream.
Mizuki stomps back. “Mom, Dad, Uncle Hanbee said to ask you.”
Suzuya pokes his head into the room. “What’s going on?”
“Where do babies come from? Why can’t I know?” Mizuki complains.
“Oh hell no!” Keijin scurries past.
“Aliens,” Mikage says seriously before following Keijin.
“Squad Leader, stay,” Mizurou begs.
“This is your turn to shine, Mizurou,” Suzuya says with a grin.
When it’s just the three of them, Michiko sighs. “Let’s sit down, Mizuki.”
