Axeloake, Zagine

ザギーネ＝アクセローク

* In the Manga
Zagine was a hired assassin who killed Train's parents. Since he was unaware they had a child, he did not anticipate meeting Train and therefore allowed him to live. Train lived with him, enduring strict and demanding training to survive. It was during his childhood that Train acquired his signature traits: drinking milk and developing cat-like reflexes. Zagine later died, leaving Train on his own, and told him that to survive in this world, he would have to be the best. That is when Train began improving himself in order to become "the best".
* In the Anime
The story is the same as in the manga, except that Train is influenced by Zagine when he reaches Eden, and confronts a "ghost" of Zagine. Nevertheless, he faces him and does not let his words bring him down.
