The Obic Seagulls made their long-awaited return to the X League summit Tuesday night, knocking off the league’s current dynasty.

The Seagulls, based in Narashino, Chiba Prefecture, dethroned the four-time reigning champion Fujitsu Frontiers in a dramatic 13-7 victory in the Japan X Bowl at Tokyo Dome.

Obic’s victory gave the club its record ninth X League title and first since 2013. The Seagulls also prevented the Frontiers from breaking a tie between the two franchises for the most consecutive X Bowl victories — the Seagulls went 4-0 in the game from 2010-2013, while the Frontiers had been looking to extend their own streak to five.
