I just made a character model of Tamaki Kotatsu for a commission (I'll be updating her to include Season 3, as well), so I thought, 'why not' and did Hibana, as well, because I like her. I want to thank my assistant, Factiis, for assisting with the season 3 portion of the dataset.
Obligatory self-promotion: consider supporting or commissioning me at https://www.patreon.com/MetalChromeX or http://www.fiverr.com/s/VY34o4m so I can continue making cool crap for you all to enjoy for free!
