It's a terrible reason, but I can comprehend it.
MABURAHO, based on the light novel series by Toshihiko Tsukiji and character designs by Eiji Komatsu, with art by Miki Miyashita. First published in 2003 and first published in North America in 2005.
PLOT:
In a world where magic is real and where the number of spells one can cast determines everything from your social status to your lifespan, Kazuki Shikimori is an anomaly. He only has the ability to cast seven after using one as a child to make it snow in the summer for a mystery girl. He also comes from a long line of powerful witches and wizards, meaning that any child he could potentially father would have immense power. That's why three girls from some of the oldest and most prestigious magic families have their eyes set on Kazuki. It's a three-way battle between the clingy and temperamental Yuna, the stoic Rin, and the bombshell Kuriko for the rights to Kazuki and his killer DNA, and all of them are determined to win by any means possible.
