GANTZ:O

Death isn’t always the end-some get a second chance, but only if they can win the deadly game forced upon them by a mysterious black orb called Gantz. On his way home to celebrate his little brother’s birthday, Masaru Katou-a kind and courageous student-is stabbed and killed. Instead of finding himself in the afterlife, he wakes up in a strange room overlooking Tokyo’s skyline, surrounded by others just as confused as he is. Before he can make sense of it all, Masaru is given a gun and suddenly teleported into the streets of Osaka with a single, brutal mission: kill every alien he encounters. Alongside an elderly man named Yoshikazu Suzuki, a beautiful idol named Reika Shimohira, and the aloof but battle-hardened Jouichirou Nishi, Masaru must face his fears and fight to survive the game. If he wins, he might just make it back to his brother. If he fails, death will be permanent this time.
