After he was able to summon a shadow familiar, Kraftvoll decided to give it a command. He shouted, "Attack them! Open a way for my Second Brother to get near my Third Brother!"
As soon as Kraftvoll's shadow familiar heard the command of his master, it immediately followed the instruction. It charged toward the enemy shortly after Kraftvoll had given his command.
Some of the seishin beasts' obedience was based on its loyalty and bond. While some of the seishin beasts under seishin practitioners only follow because of their fear of their masters.
On the contrary to that of seishin beasts', a summoned elemental beings have absolute loyalty to the one that summoned them. A seishin beast would sometimes hesitate to follow its master's command, but a summoned familiar would follow its master command even if it means of its demise.
