ONLY read the
first page of chapter 23 https://mangadex.org/chapter/813011/1 ,
DON'T SCROLL DOWN , you'll probably regret it.
'saito' means 'open' in this fantasy world's language: so morlock may have chanted something like '
open, door to another world,
open'
but the spell may have interpreted it as '
saito, door
opener (aka. locksmith) of another world' so saito was probably summoned by mistake
I feel dumb for not seeing this coming because this chapter happened
just one chapter after saito was just isekaied in chapter 22 : https://mangadex.org/chapter/804006/4 and morlock reacting quickly was even noted by mevena the shop girl
