Eiken and the nature of bad anime

Eiken (2003) is a two-episode OVA filled with all manner of slapstick and innuendo that on its face are immature and sophomoric but veer into grossly distasteful as the show continues. The question then is upon seeing this content who is it for and why does it exist?

What was the mandate that called for the product and what can be gleaned from engaging with the material?

This is not meant as something opposed to sex or depictions of sexuality, this is a question of the low quality and base manner of titillation that the show engages, though looking at the character designs and ages the author could also question what was the logic behind the creation of the characters and why were those the decisions the creators went with.
