Summary
The sun sets, and with a beat of her wings, a kasugai crow takes off.

As she leaves, she hears the sound of the gate creaking open. Dread shoots through her chest, and she flies even faster.

Summary
“I’ll be back."
Kouta nods. His chest constricts, but only slightly. His tired heart has seen this scene play out too many times to believe.
Or: Kouta is raised among heroes. It’s not as great as it sounds.

Summary
Prompt from StarfireWitch: Hunger Games AU.
“You know most survivors pick a favorite to focus on. “It’s tough to split your time between two children and get attached to both, only to watch them turn on each other in the arena.”
Slowly, as if gauging his reaction they reach for each other until they are holding hands, palms pressed flush, fingers laced together.
“That’s not going to work for us.”

Summary
“Is Eri on a date?” Hitoshi cooed, a huge, uncharacteristic grin forming on his lips. “Hang on, if Eri’s on a date and you’re here— are you spying on their date?”
“I’m observing,” Shouta grumbled.
—
Five times Shouta definitely did not trust Izumi Kouta, aka the-guy-who-once-punched-Deku-in-the-balls, to be near Eri, and one time he did.

Summary
"I should practice more.” He extended a hand to Rikido. Rikido took that as a chance to study them closer before clasping it and being hauled up. The palms were actually wider than he had thought and- were those paw pads?
Or
Hagakure, Tokoyami, Koda, Sato, and Shoji make observations about Ojiro's characteristics, it's curious and they definitely want to know more, but nobody directly asks him because they're happy to just leave it be. When they finally find out it takes them by surprise.
