Yeah, the human broom is in OAV ep 6 ^^ Ne, 
Spini, did I hear correctly that you've seen the 
TV series? If you loved Abby there, you'll adore 
him in the OAV! It's set before TV (and was made 
before TV...OAV was 1996, TV was 1999), and by a 
different staff, who DIDN'T lose track of the 
plot and heotrosexify him in a lame attempt to 
resolve the love triangle >< Apparently, the TV 
producers just kind of, um, IGNORED the OAV 
series...and the manga...both versions...-.-;; 
When you watch the end of the OAV, you will 
notice a few GLARING plot holes between OAV and 
TV due to that (example: there is a rather 
important and significant spell that specifically 
depends on everyone thinking of whom they love; 
Abby thinks of Takeo. If he had been lying, the 
spell would have backfired, big time (as is the 
rule in the MTT universe...if you aren't being 
truthful to yourself, it comes out in your 
magic); among many other plot holes -,-;;). Hehe, 
sorry, I love the TV series, but I wanted to beat 
the producers repeatedly with a stick for tearing 
Abby's character apart ^^;;

A long time ago, around two years ago I think, 
there used to be a nice cel of Abby in his school 
clothes at Taro. It sat there for a long time and 
I watched it, until it was finaly bought...it was 
about $200, if I recall...
As for Takeo-kun, he's a lot easier to find. But 
he's not as much of a fan favorite...bishy okama 
+ Koyasu Takehito's voice = fangirl fodder. Me, I 
just collect sketches and genga of the 
dear...::huggles her OAV ep 4 genga set::

All I can say is this: I doubt you'll ever be 
able to find a specific scene, ESPECIALLY the 
human broom...really, I'd just pray for a cel of 
Abby to appear at all ^^
