The sequel duology is one of the best games I've played this gen. Fair warning though - these games are VNs first and SRPGs second. You'll be doing at least 2-3 times as much reading as playing. They also contain a ton of slice of life/gag scenes which some people find slow. Story/characters are the main draw of these games but it's kind of a VLR without 999 situation if the first game isn't localized.
Btw OP the image you have in the first post is the cover of 2-2 and not 2-1.
Edit - looks like you fixed it
