He's been found and nursed by to health and ready to strike down the Androids and villains.
He found Maron unconscious and get her to the safest hospital. Kenji kind of loved Maron because she's a famous model and a pretty beautiful girl to him. After Maron wakes up she thanks Kenji by giving him a hug and kiss on his lips.
Kenji got a call from Kiyoshi and the new Z Fighters about the Androids rampage. When he told Maron to stay in the Hospital bed before he goes aby himself she refused to stay and wants to go with him.
