Ritchet is so cool, he is playable in three games, and four stories, including two which belongs to him. This is even stated in the game itself. Funny how he longs for Maria's virginity, even after she is longing for Alucards. "Ritchet: but he is like Ten thousand years old. Maria: But you met me when I was like nine....."
Rondo of Blood
Vampire Kiss
That one fight in Symphony, which is part of another game
Symphony mini-game, which him and Maria shares.
Vampire Kiss/Dracula X/Rondo of Blood/post-Symphony/and pre-Syphony are all Castlevania V. If it has it's own television series.
While not true, It is also kinda insane, of the idea, that Ritchet was so obsessed with fighting Drac, that he unleashed him, over and over, and over, and over just to face him again and again. I know it was the wizard, working beyond the grave, but man that is insane.
