"A definitive UY site which would encompass everything I love about the series. A one stop shop for all your UY needs."

Urusei Yatsura

Urusei Yatsura is a popular comedy manga from the late 70s and 80s. It is Rumiko Takahashi's first big hit, and is known for its ridiculous situations, adorable characters and cheezy puns.

The story centers around the relationship between Ataru Moroboshi, an normal guy with extremely bad luck, and Lum, a bikini-clad alien princess who has fallen in love with Ataru, as they interact with a colorful supporting cast in a town called Tomobiki.


Tomobiki-cho, the Urusei Yatsura part of Rumic World, is the oldest (March 1996) of all the subsites.

Created by Mason Proulx, Tomobiki-cho was originally launched at ottawa.net. After several redesigned, Tomobiki-cho relocates to tomobiki.com in 1997. Mason was a big part of early anime fandom on the internet, and his website can be seen as one of the "pillars" of the online anime community.

In early 2002, Harley and Dylan invited Mason to join a collective which would become Rumic World. Months later, Mason reads the email and agreed. After another redesign, Tomobiki-cho is finally re-launched with the other fansites under the collective umbrella of Rumic World.
