I think this is just about the most obscure I 
have, beating out quite a number of other 
cels I have from non-famous or non-well liked 
series (Black Magic M-66, Compiler, Detonator 
Orgun, Dream Hunter Ren, Green Legend Ran, Himiko 
Den, Maris the Chojo, Metal Fighter Miku, Mikan no 
Nikki, Romeo's Blue Sky, Ryu Knight, and Super 
Atragon).

Anyways, the samurai was a 2 OVA series from 
the 80's that features the rivalry between a girl 
fearing samurai and 2 scantly clad ninja girls as 
they duel insesently during school hours. This cel 
feature the 2 Ninja girls where one is about to do 
the naked girl attack upon the girl fearing 
samurai.
