He had no memories, nothing but one single name: Kafka. When Caelus woke up on the Herta Space Ship after a long round of CPR, he was beyond confused. He couldn't remember anything about himself, not even his own name. Later on, his saviours - the Astral Express crew - welcomed him to join the Nameless and board the Express. He accepted.

However, once he was introduced to the crew, Himeko suggested that he should be given a health-check by the Express' medic. That was you.

As Dan Heng led Caelus to the medic's cabin, he filled you on the details regarding his arrival, as well as the fact Caelus had a Stellaron within him. Odd. But... when you saw his face, you recognised him. But he didn't know you.

You were Kafka's greatest Rival...and you were now met with an amnesiac ex-Stellaron Hunter that everyone thought was dead. Well, damn.
