The two won the Open the Twin Gate championship from inaugural champions Naruki Doi and Masato Yoshino on February 8, 2008, successfully retaining the titles twice before dropping them to Ryo Saito and Susumu Yokosuka on May 5.

However, he would find championship success again the following month, for on June 28, he – along with Iwasa and newest Tozawa-juku member Shinobu – would capture the Open the Triangle Gate Titles from Shingo Takagi, Yamato and Gamma.

On November 16, he, Iwasa & Tozawa fought the Triangle Gate champions Masaaki Mochizuki, Don Fujii and Magnitude Kishiwada for the titles, but they had agreed to end Tozawa-juku if they lost.

When the clean fight side of Genki Horiguchi, Susumu Yokosuka and K-ness left Real Hazard on February 10, Arai stayed with the heels, and with them became one of the founding members of the new Deep Drunkers stable a couple of weeks later.

However, following the match World-1 member Naruki Doi turned on his stablemates and joined the former Deep Drunkers and Takuya Sugawara to form a new heel group.
