It's weird because out of context the music would just be too everywhere and disorganized for me to like but in the context of chainsaw man with the visuals I love it.
The band for this is Maximum the Hormone. They're well known for sudden transitions with no buildup that somehow work anyway. They also wrote the 2nd opening and 2nd ending for the anime Deathnote, and wrote a song about the Dragonball Z villain Freeza which was then used years later in the Dragonball movie Resurrection F
I recommend listening to the other 4 endings so far. In my opinion, this is the 4th best one. (In my opinion): Ending 5 > Ending 1 > Ending 2 > Ending 3 > Ending 4
