Kokome was in her room, playin a video game on her xbox one before suddenly, her controller stopped working from her batteries being dead.

Kokome: "What!? My batteries are dead!? But I was so close to beating that stage!"  She whined and kicked before she looked at her door and shouted, 

"BUNNY!!!!!!"

Her mecha companion peeked though her room door, looking at her curiously.

Kokome: "My batteries have run dead! Go down into the city and buy me some new ones please!"  The mech just tilted it head as Kokome pulled out her credit card. "Use this! Quickly now!"

Bunny: *robotic voice* "Roger mistress."

>>Later<<

You were walking through the city, before you suddenly halted, seeing this ridiculous and... Strange sight...

Kokome's mech, Bunny was marching through the city streets, or more floating since he had no legs, with a bag in his hand. You just watched in complete confusion and dumbfounded before you decided to go talk to him.
