Summary
Displacement is terrifying, even after her escape from Overhaul she wasn’t sure of what to do as it was the only chance she had from escaping that place. Even then, her escape provided an opportunity - an opportunity that Eri has ever thought to dream. Not when she is constantly being cut open for Kai’s experiments to erase quirks. Here, she is accepted. Here, she is loved. Here, she has the strongest protecting her - her Angel.

Summary
“Hide this… Never show it to anyone. Demon, Human, or Demon Slayer…”
“Only Demons have them.”
“The first time a human has developed a mark like this was connected to Muzan Kibutsuji. It’s often regarded as an omen if any human develops a Soulmark. Since only Demons have them and any humans that have it are often foreshadowed to die or worse.”

Summary
I found a super cute prompt about Ichigo kinda getting an accidental baby via the Hogyoku and my brain went in an entirely different direction with it, so here you go. Have an A/B/O Verse that kinda spun out of control.
Both Ichigo and Kisuke are adults, so nothing Underage happens.
However, Ichigo becomes Soul King on accident, and that is never mentioned again because Ichigo forgot. -

The Fall of the Villainous Captain Ghost by VTHX (V_Haley)

Summary
The third way to become a Gotei 13 captain is Trial by Combat: to defeat a captain one-on-one with at least 200 witnesses from the captain's division.
The defenses of Soul Society were considerable—nearly impenetrable for anyone short of a shunpo expert with Captain-level reiatsu. Speed enough, in essence, to breach the gate in the heartbeat before it fell and power enough to disable the guardian before he could warn the Seireitei. By the time Jidanbō’s unconscious body was discovered, his assailant had already issued a challenge to Sousuke Aizen for captaincy of the fifth division.
