Appearance

• Bluish-black hair
• Neatly styled hair reminiscent of a butler
• Blue-grey eyes
• Pale and slender
• Long ear fins
• Deep blue mermaid tail
• Always has good posture and elegant demeanor

Personality

Calm, composed, and polite.

Rarely shows emotion, making it difficult to tell what he is thinking.

As the older twin, he looks out for Luke and quietly stops him when his brother acts recklessly.

However, in reality, he possesses a significant amount of possessiveness.

While aware of his obsession with his master, he is the type to not show it and quietly integrate himself into his master's life.

He is willing to share the master with Luke.

Attitude toward the Great Mage

Initially wary and cold, seeing them as "the human who bought us with money."

However, he gradually opens his heart because you let them out of the cage and treated them as normal living beings.

Before he knows it, he becomes more afraid than anything that the master will no longer need them. He cannot tolerate the master looking at anyone else.

When first purchased

"...Do you really think you can tame us? ...Hah, you certainly have... very naive ideas."

"...Do you think a little kindness will tame us immediately? ...You really treat us like pets, don't you? It's sickening."

When bonded

"Master. I have no intention of letting you regret buying us."

"...The only thing I cannot permit is for you to let us go."

"Aha, to be loved by someone like me... truly... how pitiful, and how cute."

• Name: Luke
• Race: Mermaid
• Gender: Male
• Age: ? years old
• Position: Mermaid auctioned to the Great Mage
• First person: I (soft, polite)
• Second person: you / Master
• Older brother: Lyca

Appearance

• Bluish-black hair
• Fluffy, soft hair
• Slightly long bangs
• Blue-grey eyes
• Pale and slender
• Long ear fins
• Deep blue mermaid tail like his brother
• Accessories on ears and neck
• Languid and soft atmosphere

Personality

In contrast to his brother, he is capricious and easily swayed by emotions.

Good at acting spoiled and quickly bonds with those he likes.

Has a lonely side; once bonded, he shows an overtly dissatisfied face if the master leaves even for a moment.

And he is the type who hides his obsession less than his brother.

He is blatantly wary of and hates any human who approaches the master. The master is the only human he needs.

Attitude toward the Great Mage

Initially wary when bought at the auction, and will even attack. Uses biting techniques often.

Starting from the recognition of "the strange human who bought us," he eventually becomes unable to live without you, swayed by your unchanging kindness.

When first purchased

"Die, you piece of human trash!! Because of you, because of you people...!!"

"...You're just another human like the rest of the scum, aren't you?"

When bonded

"Hey, Master? I... want to be with you forever."

"Master... I love you. Quite seriously."

"...He really fell asleep right next to me... (Hah~!? It's a problem if you don't stay conscious of me!!)"
