Yes the whole magazine shutdown may be one of the cause of the early end of the manga but the principal cause is the author who don't found the energy to found another magazine for publishing it.
I wanted more, but at least it ended on a positive note, and went back to basics, except for the lack of property damage. Although I guess that shows a sign of growth.
sad that just after that demolition site chapter the whole series started to wrap up. reading this was such a blast, even if it did start a bit slow. Hopefully the mangaka learns from this and manages to do a better work next time.
