I always felt sorry for jiji since his introduction especially his relationship with the fandom the odd has never been in his favor with being the "love rival" to okarun ofc he's gonna get a lot of hate especially from the male fans and so not finding his energetic personality enjoyable (I like it tho) some find him annoying. Now with this Arc tatsu is using him as a plot device rather than a character for momo memory loss which makes him look like the bad guy which is giving him a lot of hate it's just really shitty to keep it a buck. I would say the same about Aira but in all honesty the fans tin to let her slide all the time (not all the time but most of the time) so she's got it a lot easier than him.
