Hate to bother you guys, but...I love that OAV 
myself. ^_^

Note:  I'm actually not looking for Tsunami.  I'm 
looking for the heroine or her fiancee, Eiji.  
Such a sad story.  *sniffles*

BTW, the reason they're so rare is because they 
weren't publicly released--the producers and 
animators sold the cels privately among 
themselves, and from there, only a few escaped 
onto the open market.
