Eiya.'s Links
There was once a budding romance between the two, but that had quickly faded, and was replaced by platonic friendship instead. Eiya isn't protective of many people, but he is protective of Muffett.
A sentient puppet doesn't have many friends, but Eiya is one of the dearest. Their relationship consists of mostly brief conversation as they pass each other by, but Muffett always looks forward to it.
Klaus is entertaining, more than anything else, to Eiya. Klaus often is his opposite, and while the two do oppose each other at times, they respect each other.
Eiya is the only one stubborn and carefree enough to make him drop his guard, just a little. They're not truly friends, but Klaus feels that he can trust Eiya enough with most things. He does know, however, that the elf would throw him under the bus if it ever came down to Eiya or himself, so their relationship is a cautious one.
Eiya pities her most of all. He's heard terrible things about what has happened to Marigold, and knows that her cut tongue has caused her practical mutism. If any of them were to break free and get revenge, he hopes it'd be her.
She enjoys Eiya as a person, but wouldn't give him the benefit of a compliment, even if she could.
