Yu Yu Hakusho (2023)

Kind of similar concept here both the drama's protagonist fight again ghostly being that enters in human beings

The second chance is v similar. Also the yonkai thing that they’re looking for is almost the same concept. Overally the concept is v similar.

Both MLs end up dying saving someone and travel to the underworld which, due to the circumstances of their selfless death, allows the ML to have a special job and a second chance.

Adaptations of a manga / comic with a complex and interesting lore with supernatural elements.
Both dramas shows young and charismatic characters growing, getting stronger and making friends along the way while fighting evil / saving the world. Classic shônen vibe.
They have great actions scenes with satisfying visual effects.

Excluding the romance in TOTNT, the short presentation of YYH sounds eerily similar to the basic plot of the other drama. I haven't watched the anime, read the manga or plan to watch the drama for YYH, but still... "working for boatmen of afterlife" - check, friends with the (friendly) Death Gods - check... Sounds like at least some of the premises are similar.
