This game should be simple yet fun. Take three anime's that you know and combine them together to form a new one, using a combination of all the titles, the main characters, and the basic storylines. I'll start with an example:

Kenshin Ball Frontier:
This story is about Kenshin, a Samurai seeking to redeem himself for his past sins, while journeying into outer space to establish a new colony while accompanied by his friend Ranka Lee, who tries to find out more about her own origins and singing career, and their son Gohan, who learns to control his powers and balance saving everyone aboard the colony ship with his own career and education.
