@BroederTrapist same with the cringe thing , but honestly the target of summonings in some cases are ppl exactly like ''that'', ppl that are easy to manipulate coz they either dont think things properly or coz they want to show off, one is a 16 dumbass that thinks hes already cool so its easy to manipulate him by giving him a cool tile like ''Hero'', the other one is a 23 ''individual investor'', just by that and his thing about strategic magic we know that he thinks hes smarter than everyone and he probably couldnt find a company job due to his inflated ego, so he works freelance, and finally the saint chick, her presentation alone is enough evidence of her lack of self-esteem, she says shes a college student and that she has been looking for work for 1 year without results, this plus her Saint job, set her up to easily manipulate her by using guilt, she now has the potential to ''save'' everyone, how could she even think of not doing that?
and the MC, dude is 60 years old, im guessing this plays with the troupe of good life filled with good actions so u can achieve Godhood, ive seen this thing in at leats 3 more isekai mangas, so no wonder about his God job, im guessing that the god in charge of transfers was like: ok these 3 are gonna be easily manipulated so i better put someone with a good head on their shoulders
