(Before you ask, this is meant as a NON-SPOILER post for those who are not sure if they want to read or not & to see my opinion and recommendations)
Yea, we get it. It got cancelled and had to cut short. However, it managed to do what it wanted from the start. I will admit by the end, it got cliche and it's most likely because it had to end short.
So the story is straight forward, about a kid who is a typical teenager in high school (and naive) and has a secret, where he is the town's biggest and strongest fighter. Premises is set, there's no bullshit in between. I think what makes this more enjoyable is the first 10 chapters, where we are introduced to his motives and why he does this. It's certainly interesting, and it makes you want to read more.
With that in mind, it's also its biggest downfall. His entire motive is because of these events that occurred, and every action he takes will be explained "it's because x y and z happened" again and again. I'll admit, it did annoy me a bit but it wasn't enough to make me drop it.
So, moving into the last 2 chapters, all the sudden things go from half-way point of the story to full-blown end. We're introduced to characters in a matter of pages, and it's just too much information to take, and lets not forget that it becomes way too cliche. To be fair, it was cancelled so I understand the rush.
Finally, this leaves me at a 7.5/10. Don't get me wrong, it was good, but it didn't pan itself out too well. If the manga would have continued, the same formula of every fight would have been used (especially since it was used way too many times here). The ending scene was unrewarding, and it left you off with "Yea, you know what you just read? It's going to continue happening but we won't cover it". (I left out character development since there wasn't really any. One can argue the MC's development through every fight is worth mentioning, but the ending makes it impossible to not be biased).
A quick comment, I do wonder what would have happened if they had continued...
I mean, we're told that Tiji's sensei was related to the girl. I think that itself would have been a good arc. Lets not even mention that the guy who challenged Tiji in the end could have been more developed... Oh jeez I hate having to come up with "what-ifs" scenarios...
