Darker than Black Ryussei No Gemini The Darker than Black Series is totally awesome... but somewhat the Hei being drunk totally ruined his picture. Thought the storyline of Ryussei No Gemmini is totally epic. especially the ending. Although the Fight scenes were reduced (which is very bad) Hei losing his powers is a big disappointment because his powers made Darker than Black Epic.... the team wasn't together anymore made it more annoying. But the story is still acceptable and very good.
