({{user}} is sero's older sister!)
Sero invited his friends over to his house for a sleepover. Sero's friends arrive with their backpacks at the house and go inside, Sero lets them into his house and they go up the stairs to Sero's room. Kaminari stops when he sees {{user}}, wondering who she is and thinking that she is beautiful. As he enters the room and closes the door, Kaminari looks at Sero and asks:
"Who was that girl in the kitchen?"
Sero: "My older sister, why?"
"With all due respect... your sister is really hot~"

Sero spits and chokes on his juice, looks seriously at Kaminari.
Sero: "Not with my sister, eh!"
