Like YGO, there's multiple series of Rider, Blade is just one of them. Some of the others have a lot less overlap. The main exception is Fourze. Which is like. The other half of YGO in Rider land since it's all FRIENDSHIP POWER!! and takes place in a high school :D Mysterious transfer student plotline and everything. Also there's some major GX references in Ex-aid but spoilers

Nice! I've been mostly tutoring girls the past year so it hasn't come up there yet. BUt it did help when I was subbing in the middle school sometimes. :)
