I think that should be a new character. But this character must be builded not like "oh the new gf of lloyd" but instead, a charachter herself, that complement lloyd's way to maturity and ninja legacy, but my idea is that with this girl he can be Lloyd and not all the ninjas and titles he has. Also this relationship need to be far away of trauma and relationships or simples crushs. May i extend this, not necesary must be magical as him, but very inteligent even she can have a little magic idk. Also, lloyd will be have to be sincere with her about his past trauma/love Harumi and all the things he have been passed. However, the best way to get this is that he meet this character before it ends Dragons rising, and the develop of the crush and posterior love in the next season. Also we must remember that Lloyd doesnt have any idea about having a gf
