Riko Tachibana x Luka collaboration song. Even the people you feel you can rely on might be dangerous people if you trust them. People who talk like they know themselves. But there are dangers lying around just by living, so I head for the path I believe in, no matter what happens. From now on, we will become stronger and stronger, so isn't a dangerous thorny road just right? A strong song from Riko Tachibana and Luka!
