The Return of Titas (タイタスの帰還 Taitasu no Kikan)
While training, Titas explains to Taiga the circumstances of how he came to Earth. He was attracted to Nana Kujo's strong feelings in the same way Taiga was to Hiroyuki. As Taiga and Titas continue their conversation, they come to the conclusion that it was nothing short of a miracle that they managed to find each other in the same world, and that it was simply meant to happen. They talk about Fuma, and Titas reassures Taiga that he would pop out of nowhere eventually. Taiga also wants Titas to stop training while they are having a conversation but Titas says that spending the last twelve years as particles has caused his body to go out of shape, but it's stressing Taiga out. They continue to talk about Fuma, saying that once he returns the Tri-Squad will be together again, and then reminisce over past events.
