Break Chance Memento [v1.3] [Cyanide Tea] v1.3

One fateful morning, Shuuki stumbles across the gruesome sight of his brother Masaharu’s corpse. When all hope is lost and Shuuki must come to terms with the fact that his brother has been murdered, the mysterious Kyousuke appears before him with a proposition:
“Do you want to bring your brother back? To fix your family’s broken relationship? You can…if you learn to travel through time.”
Before he knows it, Shuuki is caught in a plot far more sinister than he could have ever imagined. He learns that the key to traveling through time and stopping innocents from being killed lies in mementos: items that are a link between the past, future, and present.
