Manga 162479 Kagurabachi Userrecs

Main characters in both of these two stories are male teenagers who want to, among others things, avenge their fallen relatives and get revenge. To achieve that, they become swordsmen fighting with katana and using special powers to fight their enemies (in Kimetsu no Yaiba's case those powers are tied with Breathing techniques, while in Kagurabachi's case - with blades enchanted with magic). Both manga series feature blood and gore during the action scenes. 

The story isn't similar actually, but the thing that I think is pretty similar is the panelling. Both panelling are very cinematic and very creative. 

Both main characters use a sword, both have powers using the sword and both lost their dad at the start
