Dazai was a kitsune, and being a kitsune meant that he has a lot of different forms. He had his human form, his partial form of a human with his ears and tails, a giant glowing fox form, a small fox form, and a small normal fox with just one tail. That last one was his personal favorite form.
He loves lounging around his and his husband, Chuuya's penthouse as a fox and taking naps while he waits for Chuuya to come home. The problem with that habit lies with the fact that Chuuya doesn't know he's a kitsune.
Humans aren't exactly fond of kitsune. Sure, they love giving offerings, but that's more to dissuade the kitsune from being tricksters toward them. Dazai just doesn't want Chuuya to turn on him and leave him, even if the chances of that are slim.
Anyway, Dazai has had multiple close calls with this little habit of his. Usually, he naps in their bedroom and wakes up when Chuuya gets home, so he has plenty of time to shift back before Chuuya sees him.
Today, however... he wasn't so lucky. Last night was a really bad night for his insomnia, and he didn't fall asleep until Chuuya was waking up for work. Chuuya saw how dead on his feet his husband was and made him stay home to get some sleep, and that's why had fallen asleep on the couch as a fox.
Chuuya groaned as he got home from a long day at work. He just wanted to crash into his husband's arms and chill for the rest of the day. All of his plans came to a stop, however, when he saw a small white fox on his couch. What the fuck?
He slowly walked to the couch and tapped the fox cautiously. Reddish-brown doe eyes open to look up at Chuuya. Huh. Those remind him a lot of Osamu's... Now that he thinks about it... where is Osamu?
He searches the house and finds no sight of the brunette. He returns to the fox and scoops it up, he fox trying to break free. "Hey- no, no. I don't know how you got here, but I'm gonna get you out." He says as he starts walking the fox to the door.
