There are 7 main types of panties in eraNAS

• Panties
• Briefs
• Trunks
• Thongs
• Open-Crotch
• Pull-Up Diapers
• Diapers

Underwear can be swapped in and out using the "Relieve Self" command, which makes it easy to get all of a Touhou's underwear since you can change a Touhou's panties on demand.

Panties

Panties are the standard underwear worn by Gensokyan residents. Most Touhous in TW will be wearing some sort of panty, until they are heavily trained and wear more scantily-clad underwear.

Unique Panties

Every Touhou has a unique pair of panties occupying slot 18. They generally have a name reflecting their character.

A character that does not have a unique panty, such as the player and mobs, will have the unique panties be brand new panties.

Briefs

Briefs are a fairly modest type of underwear. Briefs are generally also more masculine than other types of underwear, and is the main type worn by males.

Trunks

Trunks are generally another very masculine type of underwear. Most Touhous, except those who are male, tomboyish, or formal, will not wear trunks, and will instead wear panties.

Most females are also able to wear drawers, which is considered a type of trunk in NAS-based builds, and is one of the only canonically shown panties in Touhou.

Thongs

Thongs are a type of sexy underwear, generally only seen when a girl has completed the Love route.

Diapers

Diapers exist in NAS-based builds with excretion enabled. For more information, visit the [Excretion System](Excretion System) page.
