No date announced yet. Image source is from the official website. I will updated this when I find an English language article (edit: Crunchyroll source). Synopsis of the light novel source from AniList:
Makoto Misumi was an average, everyday high schooler, who found himself shipped off to another world at his parents' whims. Upon arrival, however, he's insulted by the Goddess for being too ugly and thrown into a desolate wasteland. He frantically searches for human warmth and connection, but can find nothing but monsters and inhuman settlers. When he finally meets companions he can trust, they turn out to be a pair of powerful perverts in a former dragon and a former giant spider! His high-octane, incredibly misfortunate trek through this foreign world has only just begun!
This is as surprising to me as it getting a season 2 was. And I'm sure it's a completely normal, company purchasing rights to adapt and expecting returns... but part of me is like... what if it's just one really rich dude that wants to see it animated? ๐
Agreed. I am really surprised as well. I wouldn't be too surprised if you told me that it was the studio director's favorite series or something like that. Then again, maybe it is way more popular in Japan?
