The 172nd chapter of Sekirei by Sakurako Gokurakuin, serialized in the seinen manga magazine Young Gangan published by Square Enix.
Plot
In an extended flashback, Karasuba reflects on her first meeting with Yume and their subsequent experiences as the Second Generation Disciplinary Squad. She remembers Yume telling her after one engagement that she should not just go around killing humans; and at that moment she snaps back to the present, where Musubi has just blocked her attack on the invading soldiers. Musubi reiterates that Yume's spirit has now completely fused with her own, thanks to their bond with Minato. Karasuba interprets this as Yume having been killed by them, and she swears revenge; but Natsuo arrives before she can take any action.
