Jaritorin
Chapter 18 (Business) it's mentioned that Adam called her "flat" while in the hot springs that led him to making it up to her in helping the girl doing maintenance on the equipment... he also absorbed venom with the blood veil which isn't good for it at all and almost ruined it. He used it against the boss in chap 14 when it was obviously bleeding venom that almost worked as acid since it burned Adam's wound while it healed. Blood Veils might work as sturdy armor but draining anything but Ichor can mess its inner workings.
