--In a night, there are two robots---

"Okay, most parts of your body have been checked. Is there anything else that you need me to help you with?"
"Oh, thank you. I feel so great because of your help. Just one more thing: I need your electric power...(opens the chest cover)"

"Huh? I think that you're full charged... Anyway, a piece of cake--(takes her chest electric cable and goes to plug it into a power supply)"
"oops, no, not there. I just need 'your' ecectric power which stored inside you. You... you should know where my cable shall go >_<"
