Joining Class A with my wife

It appeared to be a simple test. However, some familiars forced to make a bond with a student would be difficult to display such levels of obedience. Furthermore, the old man can assess the manner of the familiar's actions. 

Like how emotions can't be hidden entirely while talking, emotions can't be hidden entirely when obeying someone. The test's goal was to find the little details in the familiar's obedience.

*Woof, woof* *Step, step* *Lick* *Tap*

The old man couldn't believe what his eyes just saw. He stared at Lupa with his eyes wide, his mouth unable to close, and a handful of wrinkles appeared. 

This was the first time he saw a familiar listening to the orders of a person they met for the first time. It wasn't about obedience anymore. The familiar Vincent had was as intelligent as his wife's familiar in the old man's eyes.
