Prince of Tennis: My Sidekick Is a Sweetheart

When Shugo Chara! meets Prince of Tennis, a hilarious and heartwarming everyday adventure begins!

A strange disturbance in space and time sends the energetic cheerleader Ran, the cool and sharp-tongued Dia, the gentle cooking expert Su, and the fashionista Miki hurtling into the world of Prince of Tennis!

Even stranger, everyone in this world can see their tiny forms!

Where do they land? Right in the middle of a disaster!

Ran dives headfirst into Tezuka Kunimitsu's teacup, Dia smacks Akutsu Jin right in the forehead, Su floats down onto Yukimura Seiichi's canvas, and Miki ends up hanging glamorously from Atobe Keigo's collar...

Four very different princes of the tennis world are forced to "team up" with these noisy little tagalongs who just won't leave them alone!

From then on, the princes' orderly lives are turned upside down.

Training camp? The National Tournament? The Shugo Chara! crew is ready for action!

[Advance warning: Some characters may be OOC, but not too badly. There's a mountain of original settings. I haven't watched the anime this time around, and when I couldn't remember some plot details, I just improvised. If you want to argue, you're right!]
