There seems to be a lot of confusion about "irregular vs regular" and "outer tower vs outside the tower."

The vast majority of people who live on any of the tower's 134 inhabited levels live in the "outer tower", the outermost section of the tower. The outer tower is also the largest part of each inhabited floor of the tower, being roughly the size of the Americas in surface area. The inhabitants can vary greatly in appearance, from humanoid to monstrous.

"Regulars" are those chosen out of the inhabitants of each floor (usually from the outer tower) to attempt to climb the tower. Ascending the tower through tests is done in the inner tower. The choosing of regulars is done by Headon. Sometimes referenced as "Chosen Regulars."

Outside the tower is a mostly unknown world (or worlds) with it's own inhabitants. Little is known about their variety, but most of outside worlders inside the tower that we've seen look human, although Pantanimum could be an exception.

When one of these inhabitants makes their way inside the tower (potentially by force), they are known as "irregulars." Zahard and the 10 family heads are from the outside world, but their status as irregulars is debated since there was no distinction between regular and irregular before they conquered the tower. Other confirmed irregulars are Phantanimum, Urek Mazino, Baam, Lahel, and Enryu. Sometimes referred to as "Unchosen Irregulars.

While there are "chosen regulars" and "unchosen irregulars", it is currently unknown if there are such things as "unchosen regulars" or "chosen irregulars."
