Honestly, all of these short stories are interesting and could be very promising, but... they never amounted to anything.

It's kind of that formula "monster of the week" (which in this version it's like "villain of the week"), but without a bigger villain or bigger... plot?

The MCs don't have a common goal, in fact, they don't have a goal at all. Mana and Yuta teamed up because, well, she had nowhere to go and apparently neither did he? But like... they have nothing in common. And this could've been better explored, but oh well... no time for character development when we have to create a brand new villain every week, huh? lol

No wonder this was "cancelled". But really, if Rumiko wanted to, she could've made this into a GREAT story.
