Who is simon belmont and why do you like him so much?
Simon Belmont is a vampire hunter.  He's the star of a few different Castlevania video games.  He's awesome.
Video games are cool. I have never played Castlevania though. What is it about?
Every 100 years Dracula rises from the dead and a member of the Belmont family has to travel to Castlevania, Dracula's castle, and defeat him.  The game series dates back about 25 years.  I own all of them.
That seems like such a cool plot. What consoles is it on?
It started out on the Nintendo Entertainment system.  But there have also been games on the SNES, Genesis, Playstation, Playstation 2, N64, and more.  It's a very long-running series.
I would lik to know more about this game. I googled it and say some animated pictures. Is it a cartoon game? 
Well, some of the games have used anime-style graphics.  And there's a TV series of it on Netflix.  I've never watched that though.
I didn't know there was a TV series, maybe I will check it out later tonight. How long is it?
I think the show is onto its fourth season.  Different seasons have different numbers of episodes, but I imagine it's pretty easy to plow through a season if you really get into it.
