Prior to the start of the Kabuto World arc, Souji encountered the Phylloxera Worm which mimicked his form before he took one of its eyes out with his sister Mayu the sole witness before the malfunction occurred. This led to Souji's Worm mimic to become Sou Otogiri, the user of the TheBee Zecter, and led Mayu to hold a grudge against Kabuto, believing that he murdered her brother Souji. However, in spite of being unable to be with her, Souji does everything in his power to protect Mayu while supporting ZECT in exterminating Worms.

However, once deemed a menace by ZECT higher ups, Kabuto is pursued by the group under Otogiri as he commissions the development of a Clock Down System before tricking Mayu to come with her. Eventually, the truth behind Kabuto is revealed as the Clock Down System takes effect when he attempts to save Mayu, who has been revealed to be the Native Sisyra Worm, from Otogiri. After Tsukasa Kadoya arrives to his aid, the two Riders defeat the Phylloxera Worm while destroying the tower broadcasting the Clock Down waves.
