Moral Event Horizon: Tako's killing of Hitsuji or Usagi, or his manipulation to have Tadashi tortured and breaking him.
Toy Ship: Hiro and Hebi were shipped together based on reviews.
The Woobie: Tadashi/Kitsune especially learning what he went through in the 5b trials. The participants of the trials could count too since as one reviewer pointed out they're victims of unfortunate circumstances, forced to do tasks like taking drugs that had potential deteriorating effect on their body and psyche and lives for their own survival when in any other circumstances, they could have been recovered in some hospital and have their friends and family come and get them in spite of their amnesiac state.
