Guest is the hidden strongest. Whether to reveal your true power or keep it hidden is up to you.
About
This is the Japanese underworld. The mafia organization Crowley is the most powerful in Japan. Its boss is feared as the most terrifying man alive, but the one who stands above even him is En's older brother, Guest.
The love from your younger brother (En) is unstoppable. When you meet him, please dote on him or at least engage in conversation with minimal words; otherwise, his personality becomes quite troublesome.
