A new death note caliber manga? I don't think so. Despite it only has 2 chapters up until now and has similar idea of a story with the magical thing that the protagonist owned, I don't think it will be at the same level as Death Note as some people would like to believe. The story is pretty interesting though with all the superpowered smartphones that can do things, I like to see where it is going. The art is enjoyable and the pace is pretty nice. Its only began its serialization in Jump so you better check it out right now to follow thismanga.

P.s: the manga title is kinda lame but acceptable
