I've been going through the 2nd cour of the 2nd season of the anime "Hoozuki no Reitetsu"（鬼灯の冷徹...Hozuki's Coolheadedness）(2018), the slice-of-life comedy that takes place in Hell. It still hasn't struck me as one of my all-time favourites, as I mentioned in the article for the opening theme of the 1st cour, but at least, it's made for some more comfortable viewing.
I couldn't find any video for the opening credits for the 2nd cour, but I was able to track down the full version of the opening theme song, "Haikei, Jigoku yori" (Greetings From Hell) performed by the main cast as the Jigoku no Sata All-Stars（地獄の沙汰オールスターズ）. Like the opener for the 1st cour in 2017, it's pretty catchy but most of it is done in an enka style this time compared to the country-style hoedown of "Dai! Jigo Jigo Bushi"（大！地獄地獄節）, although there is a semi-reprise of sorts from that song, along with a Vaudevillian "Coming Home" type of finish.
"Haikei, Jigoku yori" was created by the same folks behind "Dai! Jigo Jigo Bushi", Jun "JxJx" Saito（サイトウ "JxJx" ジュン）and Gokusotsu Ongaku Renmei（獄卒音楽連盟...Devils Music Alliance）. The premise behind the song seems to take on the feeling after a night of engorging eating and drinking during a typical enkai....something that I'd had personal experience with for many years. Yup, all of the emotions of satisfaction, shame and debauchery rolled up into one large ball.
