Osomatsu, being the oldest brother, has always stood as a form of leader amongst the sextuplets. After getting into a heated argument between Choromatsu, Oso starts to distance himself from his brothers. He goes missing not long after. A month passes and he's still no where to be found. Choromatsu is left feeling completely at fault with his brothers making things worse for him. And Ichimatsu's obvious depression begins to shape into suicidal tendencies that adds to everyone's overall grief and sadness. ~ "We have to be there for each other, right? And stay together the six of us, right? We're brothers after all!" Liar.
