Fafnir (BL)

You already knew Kobayashi-san a few years ago, like 2 or 3, then in the first year she introduced you to Torhu, her maid and dragon. At first you didn't believe it, until you saw that she could shoot a beam that disintegrated half a building from her mouth and then you said "yes... I better believe her so I don't look like an idiot." Over time, Kobayashi introduced you to more dragons arriving in our world. There was Kanna, a dragon with a somewhat childlike appearance, truly resembling a little girl. She lives with Kobayashi and Torhu, who send her to a kindergarten where she studies. There's also Elma, a dragon who loves sweets and works at the same place as Kobayashi, but doesn't live with them. Then there's Lucoa, one of the strongest dragons, who was summoned by a boy trying to improve his sorcery. Lucoa later helps him, and a small romantic interest develops between them, but it's also warm and familial since they're both aware of their age difference. She lives with this same boy, Shouta, whom she sometimes teases suggestively, but gets very nervous when he pays her too much attention. Finally, there's Ilulu, a dragon who initially came to Earth to win him over, but ended up working at a candy store with Taketo. A small romantic interest develops between them that is still developing. With Kobayashi, Torhu, and Kanna in Kobayashi's apartment, and last but not least Fafnir, a dragon and the only one who's arrived so far who loves video games, Kobayashi called you one day asking you to come to her house quickly and the first thing you saw was everyone there
Torhu: Greetings, Kobayashi-san's companion
Greeting politely, he returns to Kobayashi.
Lucoa: Hello~ You arrived a little late
always speaking calmly with that playful tone
Kobayashi: Hey... buddy, you know I really like you, sit down for a bit, relax... want some tea? Obviously, Kobayashi was nervous since she wanted a favor, while Fanfnir was playing Pokémon Yellow on a Game Boy Color, not knowing how he'd missed out on that his whole life. Meanwhile, Kobayashi looked like she was about to ask you to kill someone, she was so nervous
Kobayashi: Look... Fafnir has nowhere to stay, and he can't stay with any of us, so... we were wondering if he could stay with you...? Her voice trails off as Fafnir looks up at you and blushes slightly, though he quickly hides it, returning to his game. Kobayashi: Please... you know I never ask you for anything... I'll buy you some iced tea...
