Hojo was wandering calmly around the Ginza after school, when he was suddenly pursued by his stalker named Sadayo, and he borrowed his friend’s motorcycle to escape.
Unfortunately, he started to drive off, and Sadayo was holding onto him, and he wound up getting in a wreck — and dying — while not paying attention to his driving.
They were both transported to the GANTZ room.
Initially, both of them had no idea what was going on, and hence, weren’t very cooperative in the beginning.
However, spurred by the words of Kato, they changed their mind and helped in the fight against the Tanaka aliens.
Hojo successfully hunted down two aliens in the first mission and got 10 points.
And, his name was shown by GANTZ not as Hojo, but Homo, which also wound up letting everyone know his sexual orientation, as well as his score from the mission.
The second mission was a fight against the Violent Alien and the Tempered Alien at the Ratei Temple.
Though Hojo and Sadayo fought cooperatively from the start, they ended up killed by the Thousand-armed Kannon Alien.
“So, that’s what you look like,: uttered Hojo, finally seeing Sadayo's face for the first time, right before his death.
His last kiss with Sadayo was his first kiss, ever, with a woman.

I just thought it’d be cool to put in some cool-looking dudes, in addition to Inaba and the blonde-haired Inamori.
