Things that need to have are:

· Grimms are predecessor of hollows

· Grimms needs to have a humanoid version that is like an arrancar in hollow terms (how they evolve is in your own ccord)

· Normal grimms are as powerful as normal hollows but by some reason humanoid grimms are in the same level as espadas

· Ichigo (and if you want a friend) find there way remant

· Ichigo must be in control of his hollow mask so after hueco mundo arc anf further is acceptable moment to start the story

· It must be an ichigo and ruby story (might be harem double pairing o whatever you like but ruby must be his first and most important)

· You must give ruby a power burst to fight humanoid grimms (it can be like transforming her in a grimms version of vizards

· Give some characters a power burst (you can choose who but ruby is obligatory)

· People of bleach can arrive to remnant but only after the humanoid grimms have been discovered

· Ichigo having quincys powers
