Thanatos is here. Sort of. He's taken to helping out deliver food and drink to people and then taking way the used dishes after. He can shift locations. He's not tired. He's not emotionally drained. (Not in the same sense of others here, at least.) While he may not have the best service attitude, he does get the job done with efficiency. He even shifts outside the gym, to and from, to keep the noise low and the light show absent.

How often does one get a god of death doing fetch quests or dish pick up for you? Give him your orders.

... Or attempt to get him to join in the event, as difficult as he may be for it.
