Saint Saint X'mas Arc
Nishizawa and Yonehara participate in the Saint Saint X'mas competition together where they advance to the Top 16.

In the first round, they are selected to go ninth, pairing off against the Yamaka-Koyoshi pairing; they end up winning and proceed to the top eight, where they are matched up against Tōjō and Shizuka. Nishizawa and Yonehara step up into the boxing ring within the gymnasium together with a nervous look when they are being introduced. The two couples then listen as they are given explanations for their event: double acting scenarios. Nishizawa puts on a high performance during both scenarios; during the first, he acts out a scene where he was forced to stay present for his hamster's labor pains instead of going to a date, then in the second, he tries to protect Yonehara from a group of delinquents; ultimately, despite their high scores, they end up losing in the second round.
