Haibane Renmei (2002 anime)

This is a very old anime. 2002. To put this into words. This is a anime that wants to teach us something. He wants to teach us that we have sins. We cannot forgive ourselves because we are sinners. yet sinners that confess their sins they bare no sins. One cannot escape themselves form their sins because they know they are the sinner and cannot forgive themselves even they confess it. the whole circle continues. So, there's left the choice that others that is faithful and believe in you may guide you to the path and grant you forgiveness and lead you into the light. You want to seek for light and salvation but you must seek for help.
