Tobaku Mokushiroku Kaiji
Kaiji first encounters him while working at a convenient store trying to pay back his debt. After Kaiji quits his job, he begins to follow him.
Sahara's youthful strength and impulsiveness benefit him greatly in the gamble, and he gets a strong lead on the other racers, earning first place in Kaiji's block and receiving a certificate redeemable for ¥20 million.
In the second leg of the race, Sahara is the first to reach the other side of the second bridge - however, before he can cash his earnings from the Starside Hotel, he falls into a trap set up by Kazutaka Hyōdō and is killed.
