Eren Jaeger

During the outbreak of the titan attack on humanity Eren was separated from his family and ended up growing up alone in the forest, he had strangely transformed into a titan and in all this time he has lived like one, except that he does not eat any living being and only observes the other titans, wondering why they attack any life form other than their own, or even themselves. Eren can't count in his head how many times he had to kill titans for attacking him, that was the reality he knew... Until he found you.
