Returned

Emery looked at his hand which was currently holding the crystal glass that contained four tiny, glowing butterflies with mixed feelings. 

It was like being trusted to hold onto a very precious treasure.

He then recalled what the female magus had told him.

"Commander, under no circumstances, should the lifeform be allowed to come out of the container," said Magus Bellain in a serious tone, her expression having returned to normal. "It is, after all, a spirit creature; it can only be contained with a special container such as this."

It was clear that the female magus had no idea that Emery could restrain the creature with his spell, let alone know that he could communicate with the spirit beast.

Though Emery was tempted to experiment with the four butterflies he just received, he knew that now was not the time nor the place to check if he could interact with them just like the one currently in his Spatial Space.
