Oh yeah, Jashin-chan! I remember this! I watched this anime while it was airing back in July of 2018. It was pretty fun. I even made a review of it. After the studio sold enough DVD boxes they announced a season 2 and I remember being excited for it. After one and a half year of more anime and more personal problems I was actually scared to watch this anime. It had been so long since the first season and I thought my taste would have changed so much from back then that I would have not liked this anime anymore.
Well, after Crunchyroll dropped the whole second season yesterday and me binging all the episodes, I can say that I still like this anime.
So what changed from season 1? Not much. The biggest change are the new characters, another demon, another fallen angel and zombie + panda sibling couple. They are a welcome edition to the cast and bring in their own fun flavor.
Other then that… this is just more Jashin-chan Dropkick. The characters are still good, the production values are still solid, the comedy is as energetic and fun as ever, and the references & fourth wall breaks are still as funny as ever. The shortcomings also haven't changed either: this anime still has a problem with balancing its self aware tone with its more sincere tone and Jashin-chan can still be too much of a prick at times.
Other then that, it's a damn fine anime. If you like anime like Gabriel Dropout or Kobayashi's Dragon Maid this two seasons anime is worth a watch.
