Deconstruction

Basically, the story starts with Professor Dekapan trying to make the perfect version of a body-enhancement medicine. He ends up making a failed version instead, and things happen that results in Osomatsu suddenly developing an insatiable hunger for something.. abnormal, one not cured by food he usually eats. If he doesn't eat that something soon, it takes a toll on his health by physical, mental, and maybe social means... It is a secret he intends to keep to himself and no one else. At least until this condition goes away.On the other side, the rest of the brothers seem to have noticed the oldest growing distant from them besides his odd behavior.--(I really do not know what to say for this weird, random plot bunny. Also, bad summary and title but I tried)
