Tsubaki to One Room -Kizuna Kirameku Koi Iroha SS-

Tsubaki had been participating in the Jindou pro leagues, but after a certain match, kitsune ears popped up on her head once again. Unable to go out or train as a result, she must stay at home for a while.
She's gotten hold of time all alone with Touki for the first time in a long while. As chances like this don't come around all too often, the two of them decide to enjoy flirting, acting all lovey-dovey and doing things they can't normally do, as lovers living together!
