5 needed to calculate an average
Some weak guy finds himself in the center of gunfights between students after entering high school. In both series the story makes equally little sense, but if you did liked one, the other should prove interesting too.
Some weak guy enters some high school unknowing that in it the students are made to fight each other (including but not limited to death). Also both series are cliche and not very good, but Love Gun is probably slightly better.
