Not true. Your just observing into this way to much. The story lines are completely different. Lelouch wants revenge for being abandoned and wants tod estroy the Brittian Army for taking his freedom away. Kira wants to kill all criminals and create the perfect world and become god. Sounds very different to me.
For sure LuLu is very Kira-ish...but lets admit something. He does it hella better than Kira. And even if he doesn't I loved both shows and Characters. And yes, CC is being paid by pizza hut. But again, you know you love it.
