Also Amagiri from the first season, who was seemingly killed, but turns up alive, although worse-for-wear.
Tonally, the dog contractor's scene at the end of episode 3 plays out entirely like a death, but it's actually just the demise of her dog body, a fact that's easy to miss. She returns unceremoniously in her human body in the next episode.
Earn Your Happy Ending: Qin's shaken enough already by his encounter with the Chinese contractors in episode 2, before going through a certified lifelong traumatic experience in episode 3 as one of the only survivors of the bloodless massacre at the contractor colony. We last see him with a new set of worries in the form of the orphaned child from the colony — yet that responsibility, along with his new friend the unnamed doll, seems to have put the fight back in him. At the end of the story, it's Qin, not Hei, who's got a steady footing in life.
Love Makes You Crazy: Yin's darker powers start manifesting themselves out of a desire to protect Hei.
Manipulative Bastard: Claude, Claude, Claude. He uses his Master of Illusion powers to impersonate Amber to put Hei off balance, briefly does the same to Amagiri, then pretends to be Amagiri to get most of the EPR survivors to try to kill Hei while he slaughters the rest of them.
Not So Stoic: Hei proves beyond a shadow of a doubt his status as a Kuudere after he rescues Yin from Syndicate agents.
