I kinda feel like it should've just aimed for one volume and ended here-- it's not a bad punchline to wrap up a gag with and he did finally achieve his desire of no longer being just an R, but a desirable SR.
@Kazumaik I think the sister is not a solo adventurer, but just comes in the SR Urus.
If you recognize the exmple
In Jump Ultimate Stars (DS) Katsura from Gintama was a support character, but only on his 3-Block it becomes Katsura &Elizabeth, however Eizabeth is not aquired solo
@Bengon sorry for venting, but even if i like gag mangas to some extent i also reeeealy love a little of character development
we get a whole chapter when we discover that Urus sister is alive and they reunite, love and family, all that fun stuff...
EXEPT THAT GUY WASN'T URUS AND AT THE THIRD-LAST PAGE THE AUTOR FLIPS YOU THE MIDDLE FINGER
"oh yea, that wasn't the mc~ it was just a guy with the same face, same story, same scars, same armor~ happens a lot with gatcha prizes~ totally a coincidence~"
WE HAVE NEVER SEEN A SINGLE DOUBLE BEFORE IN THE SERIES, THAT'S SOME LAZY ASS PILE OF CRAP
