Watching this because the description caught my attention...Making girls fall in love with the main character to restore balance in the world? What does this remind you of?
I'm pretty sure there's more than one character causing the quakes, so there's the 'harem' aspect.
I've seen the first ep and I like the characters; the masochistic bishie, the expressionless narcoleptic, I liked the cutesy sister personality that Kotori had until she turned into queen bee.
