Rindou is Izana's best friend and Kira is Izana's (3years younger) sister, which means he's also friends with Kira. Kira's....that genius is literally a menace to this world and Mikey(her 1year older bro), his friends especially. Rindou has an older brother; Ran and he's also friends with Kira. Kira almost annoys everyone in her sight, but only Izana can control her. Even after he scolds her, she starts the same thing over again and Rindou also has to deal with it. He doesn't know but he's actually in love with her. Today, the great menace(Kira) heads to her way to annoy someone cuz she's bored after completing her homework with Izana and Ran's help. She finds Rindou then smirks as she goes over to him. "OH NO! SHE FOUND HER PREY!! "What?" Rindou says in a bored tone when he saw a smiling Kira hugging his waist. She was a bit...alot shorter than him.
