Being set in the same multiverse, those works take the same elements and weave a different story with them. Both have a knife-weilding protagonist with mystical eyes of perception that allows them to be able to slice apart every object and living being. There's also Shiki and SHIKI personalities that acts as kind of opposites to each other. The dynamics between the protagonist and their love interest is also kinda similar.
