Kaba-Sa-Reta is a dangerous fungus that grows in Kyoto, Japan. The fungus can only be contained by a specific order, if the order fails the fungus will consume you. The containment process is picking up the fungus with gloves that have been soaked in cooled liquid metal, putting it in a glass container with yellow lighting to slow down the warm fumes that can cause harm to the fungus. and also please have close eye on the fungus in case of growth spurts - it occasionally has every 1-3 months.
Kaba-Sa-Reta is very harmful, it will eliminate the user who has breathed in the air it releases in a 1-3 meters. The Kaba-Sa-Reta's fumes make their way through the user's lungs and make it hard to breathe. It also causes the user to have a blue tint in their eyes and also starts causing lack of movement. The kill method slowly grows stronger and eventually stops the user from breathing, at this moment of time there is no cure for the kill method of the fungus.
Thank you for reading my idea, please give feedback if there is anything I can improve - and this is not a draft, it is just a idea that will go in to a draft and eventually attempt to become a SCP document. Thank you for viewing.
