Well, I'm new in the forum, but I really wanted a Bleach Mod, so if you're a modder and you are bored or something, any help is welcome.
Well, this mod's gonna change minecraft a lot. I thought that when you start, there's a screen that explains you basic things, like: You've come here to slain Hollows as a Shinigami (god of death). Here's your sword and your detector. And then, in the inventory, you have a detector and a special sword. Once a minecraft day, included night, your detector will be activated and if you right click with the detector while it's activated, it will tell you that there's a hollow. It will also tell you the strong of the hollow and its location (in coordinates).
These are the basics, i'll edit the post if I got more ideas.
