so protag is currently in the boonies and stays there for awhile. ill spoil characters by order of reunion:
sister- she's the foster daughter if the capital guildmaster and has been sending money to protag because "he's unreliable" or whatever everyone repeats to him. when she cones back to the guildmaster to send her next portion, she's told that she doesn't need to anymore and protag us exiled. She then blows up the guild and goes to protag. raws show that they'll meet soon-ish in the manga
aunt lady- after everything that happens, police officer keeps interacting with her until she then is coerced to go on a trip to the capital or smt. her carriage is attacked on the way and she is then told that her kidnapper is involved with the police officer. after this we only hear about her again when she reunites with protag in some outskirts city. she became sex slave and when police got bored of her, threw her away in sone far away town where she's just there to keep men in the town or smt. as for her fate: she stays there after her and protag meet, and then gets killed by monsters. she then gets resurrected by protag and his sidekick, but as an undead, and then pleads the sudekick to just let her move on, which happens
saint/fiance- she's been sending letters to protag, as we know, so as events pass, saint learns that her previous secretary has been smuggling her donations. when she inquires about this, ahe learns none of her gufts and messages have been being sent to protag. when she confronts the hero about this, he just dumps the truth which makes her just give and just follow him for sone unclear reason (gtranslate ain't great). Don't think she ever meets with protag after this, where she goes ill explain alongside the hero.
mother- forget if she appeared in the manga after everything, but she's looking for job but can't cause "how dare your child he a sex crminal". she ends up in the orphanage church in the capital and just takes care of kids there. eventually meets up with protag, but keeps being orphanage person.
old guild- fails fixing the clock, which results in a huge loss of clientel. other issues ensue and then they lose everything once the whole queen looking for protag at the end of this chapter happens and stuff. they try kidnapping protag even after his strength is revealed to the world, and fail. forget what happens to them, probably doesn't matter.
police dude- does the kidnapping thing, but eventually gets caught for his crimes once the king starts looking into protag on behalf of the queen character, he's then crucified until death. one random scene that's included is that the mother fibds out about all this and takes out some anger by beating the police officer while he's crucified (that was the reason he was, for shame and for public reasons). after he dies, his soul is put into a fkesh golem that prorag kills in one of the next adventuring arcs
hero- after police officer is found out hy the king, the hero is also called her, and then is told his fate by the kibg: go fight on the frontlines. his party follows naturally (they were in fact also conplicit in sone crimes). the only exception is the saint who goes to a monastary on the frontlines, she accepts and goes tgere to repent. it's posdible thevprotag might've met her at sone point here, but i didn't see that (i just skipped to other povs and random eye-catching titles). while there, hero is weak and not doing great, so the church comes and then just tells the hero they're throwing him and his party to no mans labd and replacing him with sone strong people they found (said person's face got reconfigured to look like the hero, then antihhealing was applied to keep it that way, kinda metal). hero dies there or smt, idk.
also yes, the church is evil
