1) Ein is the karate badass alter ego of an amnesiac Hayate from DOA2, DOAD canon suggests he still uses it on occasion. 2) I like that Ein is simple to use and pretty effective as a spacer, I used him alot in DOAD and never looked back. He's very rewarding to use and to win with and his move set makes him look flashy and cool whilst doing it.
2) Dislikes: TN barely improving on him at all. Likes: His first three costumes and shades. A badass power blow. Deadly fists and badass punches (Note that his 4P+K is the most damaging strike of 70 dmg in the game when fully charged) and all of his quotes, intros, and outros.
