#BkDk #SaphThread (Streamer/Fan Pt2/2)
Everything happens faster than Izuku blinks. The DM, the phone call, the emails of flight information and hotel reservations.
He's trying to remind himself this isn't a dream, keeps pinching an arm.
And then, he's there. The Valorant Championship.

Katsuki knows how to manage his alcohol. Normally, he doesn't drink, never being a fan of the looser control he has over his thoughts.
He doesn't want to make a mistake. Say a secret, give in to an impulse...
Or sleep with his best friend and not remember any of it.

Okay! Who wants to see what I'm working on for 2026??
So, lots of HCs were tossed out in 24/25, but I couldn't get to them all.
In order to leave space for NEW ideas in 2026, I'm letting you pick the 20 I keep for 2026, and the others that get banished.
So come vote! (Link⬇️)

#BkDk #SapThread (Streamer/Fan Pt1)
Everyone needs a hobby. Something that lets them escape from their daily stress and obligations. Izuku thinks that, so long as it doesn't harm anyone, people should do what they like.
And for him? It's watching his favorite Valorant streamer, Dynamight.

Izuku loves seeing Kacchan fight. He convinces Mei to get a television in the workshop, so he can watch live battles whenever his phone alerts him.
Kacchan's fierce on the field. Dangerous to whoever he targets.
And currently? That's Izuku.

Shoto has never been the best at giving gifts. Part of it is his childhood, never fully experiencing a positive Christmas with his family.
But now, he has friends. People who matter to him. He's even taking part in a Secret Santa.
He gets Izuku Midoriya.

"Kacchan!"
Katsuki tries to ignore the annoying hands messing with his clothes. Instead, he focuses on the gremlin running into his suite.
"What's up, dragon?" He asks, watching her twirl in her dress.
"It's you and Izuku's big day!"

Izuku's body is a vessel.
He's offered it to all who need it. His head for a crown. Hands for a sword. Womb for reclaimed peace in Trev.
Using it for pleasure is too selfish for a queen at war. Too vain.
But Kacchan makes up for lost chances.

Izuku understands the importance of heats.
They make intimacy easier for omegas with 'well-endowed' alphas, increase the chances of pregnancy, and re-connects mates in a way couples wax poetry about.
But for a working omega, it's the worst.

The first time Izuku hears the myth of Kamino River, it scares him.
He sits on his mother's lap, tears wetting his face. Her story is to soothe him after seeing a bunny captured by a hungry fox in the forest.
But after fear, there's curiosity.
