RBMK takes place in Soviet Era Ukraine, mainly taking place on April 26th, 1986. It follows two young men, Corium and Leonid, and their contrasting world views. Corium believes in always taking action to help others, while Leonid believes actions like these can put yourself and others in inherent danger. As the tensions between these two reaches a peak, Corium has a meltdown of extreme proportions. RBMK has a lot of heavy references to both Ukrainian culture and historic events, but it is important to note that the creator is not Ukrainian nor a proper historian or Nuclear scientist, and to always do your own research and not take this manga as certain fact.
