If there was ever a more 00s anime than this, I've yet to see it.

Seiji is a delinquent, the toughest in school and famed for a super powerful right hand but his love life is non existent. Midori is a rich yet shy girl who wants to confess her undying love for Seiji but can't find the words, until one day, Seiji awakes with his right hand having become a mini Midori making her appearance look like a living hand puppet.
This bizarre event leaves the real Midori in an endless sleep, but Midori with her one true love embraces the situation leading to an adorable romance that may bring the nicer side out of Seiji, how will the new couple cope especially trying to hide the little Midori from the world.
I wouldn't try to understand the logistics that went into the fact that Seiji's right hand became a living girl, it's anime and it's very 00s.
The manga goes much further bringing more bizarre scenarios into the fray turning the cute romance into a harem, while the anime does go crazy with the setup, it's able to dial enough back to keep the core elements of being a romance series, that strength is held together by Seiji and Midori being made for each other and very strongly written.
The casual nudity is a bit off putting and there are one or two subplots that need ironing out but other than that, it isn't too bad.
I don't remember the dub being any good, the original Japanese voices shine here so the dub is kinda redundant.
Final Verdict: If you can turn off your brain from trying to work out how this universe works, you'll find a sweet romance anime.
