Rene Ai

Jenny Ai (レニー・アイ Renī Ai, known as Lennie Ai in Japan) is a 16-year-old girl (turns 17 during the series) who is friends with Joe and Mike. She is a no-nonsense girl-next-door, determined, stubborn, but also caring about her family who faces Hazzard's machinations. She is the second of the group to operate a ninja robot; she pilots the Phoenix Thunderhawk. She is almost as daring as Joe in combat and comes to his rescue several times.

A local boy, Kenji, has a crush on her, but she does not reciprocate, and gets irritated whenever Joe teases her about him. She is passionately in love with Joe and is very jealous and possessive, becoming upset and hurt by Joe's continued insensitivity to her feelings and occasional flirting with Princess Romina. She reacts violently whenever she observes signs of Princess Romina's increasing love for Joe. The two girls reach a true when Romina admits loving Joe, but requests her for a united front until Ladorio is freed. Although Jenny does not like going to Ladorio (fearing she may lose Joe to Romina), she changes her mind when Joe confesses his love for her. Jenny is also close to Mike, giving him advice on courting Jade.
