Les Yay: Albeit onesided from Kosame towards Kiriei.
- In the 4th episode, she straddles Kirie in bed after stripping down to nothing but her unbuttoned shirt and panties, while panting and blushing about how she wanted Kiriei to be hers. And is only narrowly prevented from raping her by Lisa and her maids, who inadvertently knock Kosame into the wall, while chasing after Yukinari.
- During their match in the girls fight competition, Kosame drops all pretense of grapling with Kiriei and goes so far as to lay atop her while slipping her hands under Kiriei's bra to fondle her directly.
Kosame: (dreamily, nuzzling Kirie's breasts) "Oh, Ms. Kiriei, ever since I met you, I've wanted to do this. Your skin is perfect."
Kiriei: (trying to crawl away) "Make it stoooop! Quit it!"
Kosame: (happily nuzzling Kiriei's back) "Uh-uh."
- The same episode has Kosame save Kiriei by taking a punch from Lilica for her, during the finals. While Kirie was disappointed that they lost, she was touched by Kosame's gesture and relived that she hadn't been hurt; prompting Kosame to kiss her.
- A later episode has Kosame chasing Kirie around the house while calling her "big sister". Which Kirie points out was ridiculous since Kosame was older than she isnote . Still, after Kosame tackles her and begins happily nuzzling her cheek against Kirie's boobs, she sighs and finally relents.
Kirie: (mumbling, with wry grin)
"Fine, you win. I'm your damn "big sister".
