How this all happened

School uniforms challenge

I wanted to use anime uniforms but you are probably not dirty weebs like I am
most likely
I still should've used them

From the Northern Land, towards the later stages of the Rain Calendar, we've got a more clear depiction of the Shigu Defense Force "Vanguard".

This Northern Sergal is wearing clothes and armor made out of a Talyxian House Pecker.

The organic mask on the Sergal nose is a living and breathing Talyxian organism which acts as an extractor, filtering the Talyxian Biome's Miasma and providing the sergal with the ability to breathe within the depths of the Forest.

The Talyxian mask slithers down a tentacle through the Sergal's nose cavity, all the way down to the lung, filling it with filtered oxygen directly.
