Phosphophyllite is one of the weakest houseki, mineral life forms composed of microscopic organisms, and for the longest time has not had a job or purpose until one morning when it’s decided that they should create an encyclopedia. Few of the houseki know much about the topic and Phos is soon directed toward Cinnabar, who keeps their distance from the others due to the poison their body produces. But after seeing how much Cinnabar is suffering from the situation Phos instead resolves to help them find a meaning for their existence.
A coming of age story with a moderate amount of action, large quantity of comedic banter, and a bit of mystery.
