>>280434106 (OP)What are you even confused about?
Guy does some shady ritual, gets isekai'd to some victorian not-england, his memories fuse with the memories from body he inhabits, magic police tests if he is behind the magic suicide, then they decide to recruit him since he's involved already.
Then he gets some training, picks up a potion that grants powers (thinking that having magic powers will make it easier to return home), recreates the ritual and finds two people who also used some mystical shit. Then he goes for two missions involving magic powers, kills a clown that wasn't clown (he was some other sequence?) and that's it for now.
