Information on the THREE "Kakyuusei" (or "Kakyusei") anime
There are two good English webpages about the Elf version Kakyuusei OVA (4 episodes)(1997-1998 ) and Kakyuusei TV series (13 + 1 bonus episodes)(1999):
You can find your information on the two of them there. But I just wanted to state this clearly so that they'll be no confusion. There are THREE anime with the title of "Kakyuusei or Kakyusei" (spelled either way). The oldest Kakyuusei anime from 1995 is unrelated to the more recent two Kakyuusei anime from 1997-1998 and 1999. Here they are in the order of their release. The easiest way to tell them apart is by examining the girls school uniforms:
1. Kakyuusei OVA (4 episodes)(1995)
The girl's school uniforms are orangish-red and white with light green trim.
2. Elf version Kakyuusei OVA (4 episodes)(1997-1998)
The girl's school uniforms are mostly dark red with dark blue trim.
3. Kakyuusei TV series (13 + 1 bonus episode)(1999)
The girl's school uniforms are mostly dark red with dark blue trim.
The first two episodes of the Kakyusei OVA (1995) were released in English under the title of "First Loves" by SoftCel on VHS. The third and fourth episodes were NEVER released into English. The story of this Kakyuusei anime was not based off a game.
The Elf version Kakyuusei OVA (4 episodes)(1997-1998) and the Kakyuusei TV series (13 + 1 bonus episode)(1999) were based off an ELF company ren'ai (romantic love) game called "Kakyuusei". Kakyuusei is one of the most popular ren'ai games of all time.
(There are also the two or three "Kakyuusei 2" anime, but I'm much less interested in "Kakyuusei 2" than "Kakyuusei". :P )
The Age Rating of The Three "Kakyuusei" Anime
Kakyuusei OVA (4 episodes)(1995) - each episode had adult scenes so all four episodes were adult. It's an old adult anime though so the adult scenes are pretty mild compared to todays adult anime standards. ^^;;;
Elf version Kakyuusei OVA (4 episodes)(1997-1998 ) only the fourth episode had two minutes of adult content in the adult version of the fourth episode. There is also a non-adult version of the fourth episode with a scene of Mizuho brushing her teeth and a couple of additional scenes of dialog near the conclusion. You could technically call the non-adult version the "official" version now because Pink Pineapple chose to release only the non-adult version to DVD and not the adult version. You can't see the adult version of the fourth episode unless if you buy it on old LD or VHS formats (Although you're really not missing much in the H-version anyway - just 1 minute 52 seconds of soft H scenes without much dialog).
Kakyusei TV series (13 + 1 bonus episode)(1999) was completely non-adult of course (unlike certain eBay auction seller's claims to the contrary >_<).
