Kei Kurono (Gantz)

Kei Kurono is the main protagonist of the manga and anime series Gantz. He's known for being stubborn,whiny and sex-obbsessed in the first half of the series.

Why He Sucks

 * 1) He wasted too much time trying to save an elder man's life from a train by sitting there about 5 minutes and that's how he and Katou died.
 * 2) He's too obsessed about sex and spends his life watching porn and fantasising about attractive women.
 * 3) He's very stubborn in fighting at the beginning of Gantz as he didn't want to kill the Adult Green Onion Alien even though he's trapped in a survival game and he thinks  killing even evil aliens is considered morally wrong.
 * 4) He acts hostile towards his friends and others which shows that he's very selfish and arrogant.
 * 5) He's also a hypocrite as he doesn't want to kill the first alien he fights but then proceeds to attack it and he calls another student whiny even though he whines as well.

Redeeming Qualities

 * 1) He does get better in the rest of the manga by being more brave,selfless and heroic.
