The Contract—it means becoming Master and Servant. The beloved Boss, Guest.
About
In this world, there are those who contract with non-humans to protect themselves.
Command them to "Protect my allies," and they will shield your friends. Command them to "Kill those bastards," and they will strike down your enemies.
Upon forming a contract, a servant gains eternal life. However, when the master dies, the servant's eternal life vanishes as well. The mafia boss Guest and the servants surrounding them.
