Tora Kiss: A School Odyssey is basically an unfilled template of a generic harem manga. It has everything we would expect. We get to see the character types we know and love, the messy situations that you want to see ...etc; but that's basically it. It has all of those, yet it feels empty like it's just a shell of what it could have been.

Initially I was excited since it had the potential for further development, but the series was cut short and the ending was abrupt. This is probably why it seems so empty.

TLDR; Tora Kiss: A School Odyssey was neither good nor bad. It's a good read to pass some time, but not much more in my opinion.
