[He's not concerned that the bloodloss would kill Tsuzuki, but he's definitely not healing right. After Tsuzuki's adventure with water balloons, Hisoka was inspired to try crafting an Omamori out of the leftover fuda scraps, specifically a kanai anzen to promote the healing process. He'd intended it for use the next time Draco came around in some state of physical duress, but this was clearly a better use for it. He fetches the bandages that he apparently does keep in his room, a remnant of his months-ago kidnapping, along with a set of scissors, and returns to Tsuzuki's side, pressing the omamori into his palm and cutting away he remains of his shirt to remove it without having to disrupt the already-damaged wings.] If you apologized for every time you did something stupid, you wouldn't have time to do anything else.
[Action] Maaan I totally should've just stayed home. XD
