"Mana supply is a holy deed, so we're not embarrassed!"

At Witch School, girls are trained to produce the best "mana supply" (sperm).

Sex is no mere leisure activity, nor is it a brutal affair.

Students are arranged in boy-girl pairs to ensure a constant supply.

Mana enhances a Witch's powers so she can battle the Eaters!

It's in everyone's interest that everyone master all kinds of sex technique.

More pleasure, better mana. Better mana, stronger Witch!
