Towa no Quon 1: Utakata no Kaben, Zettai Karen Children: The Unlimited - Hyoubu Kyousuke Recommendations
Both main characters are near indestructible and trying to protect others like themslves from the normal humans who fear and hunt them.
Both are dramatic; Both got really "hard to kill" main characters that have been betrayed in the past (--> epicness); Both got action; Quon got nice ost (I'd say Quon a little more overall quality ;) )
- The main protagonist in both these series are quite similar because they both believe in helping other people who have special abilities.
- Both series include government sectors trying to hunt down the people with special abilities.
- The main protagonists in both these series have been alive for quite some time as well.
