Firstly the story is very engaging and funny, the humor can be rather dark and filthy with it's it's strong language, sexual harrassment and comedy violence but it sets the tone with what the band and Krauser II are all about. It's fun to see Negishi use his alter ego Krauser II to his advantage through his day to day situations and events, not for selfish reasons but rather for helping out others, getting himself out of tough scenarios and for pleasing his manager the 'President'.
The characters are very refreshing and funny, Negishi is a very polite soft spoken man compared to the filthy mouthed violent Krauser II, it's great to see him as his alter ego, particularly in situations to get him out of hot trouble. The other supporting characters are interesting such as the Death Records Manager called the 'President' who doesn't take no for an answer and doesn't take fail too lightly, there's Masayuki Wada as the bassist who would much rather be in a visual kei band, Terumichi Nishida the drummer who speaks few words, and Nashimoto Keisuke as the S&M mascot of DMC called the 'Pig of Capitalism' who get's beaten and abused on stage. Lastly and importantly there's the love interest of Negishi called Yuri Aikawa, and of course, the fans of DMC. The fans make the episodes very entertaining, they're funny, crazy, over the top and treat DMC and Krauser II as the holy grail, such as punching and fighting anyone who opposes Krauser II's name and creating rumors and legends of the band. There is not much character development except for Negishi but it is cool to see the back story of some of the characters and how they act outside of the band.
The animation I find is really good, it's old school looking but I think it adds character to the story. I find it rather appealing and goes well with the softness of some of the characters and it goes well with the more edgier scenes with the band. It doesn't distract at all and I think it gives such a lovely distinct style to it.
The music is very good, it sets the tone for each scene whether it's whimsical or comical. The opening song shows the type of music that DMC plays and while I'm not much of a death metal fan it did grow on me. The ending song is more soft pop and that's what I like about the opening and ending song, it shows the opposites of Negishi and Krauser II.
Overall I enjoyed this anime and I would recommend it, it made me laugh and kept me engaged throughout the whole experience. The only disadvantage is I wished it was longer as it has only left me wanting more but I know it'll add to the fact I'll most likely watch it again in the future. There could have been more closure to the story or more insight into the characters but overall this anime is fun to watch.
