Fics like An Hourglass of Stars

When an unconscious Judai appears mysteriously in front of Yusei, Yusei has more questions than answers. And when Judai awakes and remembers little of how he got there himself, the mystery only deepens. Now, with the WRGP already close on their heels, Judai will team up with Yusei to fight this new threat - but what was the reason for Judai's appearance in the first place? [ported from FF.Net cause Ao3 is nicer]
