he's really lucky that the author gave him time to know how shitty his party member is and let us know his backstory before any of them decided to kill him, if not he would have died cuz he somehow didn't do the gacha until he's done telling us how doomed he is.
i hope he wouldn't wait too long in the future, if someone is trying to transform you gotta attack them, if someone is suspicious you gotta be warry, if you think you saw something don't ignore it with "it's just my imagination..", i just hope he learned something from the adventure with his former party, also why did he go to the front again? that was too reckless, is this perhaps his first time adventuring? cuz that would answer why he's so naive
