So many things I imagined in the novel that are different from the manga...
First, I thought he killed himself beating his head against the tree
not by the truck.
Second, the slime suit, I imagined it as a full body leotard with a mask. Well, in the beginning he didn't wear any mask...I think...
Third, the possessed girls, I imagined them as a black slimes, not the cute type slime, the gore type one with body parts inside and all.
Anyway, all this may be just due to my shitty memory XD I don't trust it at all XD
Maybe I will re-read the novel to confirm....naaaa, too much trouble
