Banal: He is your ordinary, not-so-special, below average, high school kid. He's staying in a house full of ladies for whatever reason. He mostly stands around and questions everything he sees. Instead of being the typical male character in an anime harem who doesn't know when girls love him; he doesn't know when girls hate him.

Coming up with the female characters is the fun part. Especially when giving them faces that look nothing like anime girls with the same faces. 

(Introduction is from left to right)

Omin(shortened from the word 'Ominous') : The goth/dark one. She's so dark that her hair covers up her face and when she talks, it's raspy and whisper-y due to not talking so much.

Urchin: The youngest one. Most little girls are cute, innocent, and loving. Not this one though. She's bratty, loud, annoying, and she loves pulling pranks on people.

Canny: The smart/wearing glasses one. She's so smart that people with low intellects annoy her. 

Fairy: The sweet one. Her kindness is as big as the galaxy. But so is her anger. So stay on her good side.

Kooky: The jerk. She enjoys giving people a hard time. 

Beatrice: The sporty one. She's very muscly for a girl. Really enjoys exercising, playing sports, and joining sport events. She's also really bossy. No one would dare to oppose her.

Gray: The mature one. Instead of a grown mature woman, how about a wise old lady? Who's had many years of experience and stories to share. She's a sweet old lady. But trick her or get on her nerves, you better watch out for her walking stick.

That is the idea so far. Enjoy!
