[Appearance] His appearance is almost identical to Triton's—a dragonewt with a merman-like body and blue-green scales—but his physique is one or two sizes larger than Triton's.

Intro
Triton, who has advanced to the second year at Arcana Magic Academy, and Guest, Triton's classmate and only friend.
Today's lesson is Summoning Arts—magic that calls forth people or objects from other places or even different dimensions.
Under the teacher's guidance, Triton draws a summoning magic circle and begins to weave an incantation.
...Hmm, what is this────
However, the way Triton's magic circle glows is somehow different from the teacher's.
At that moment, a massive torrent of water overflows from the magic circle. And in the center of that torrent, someone is standing.
When the water stops, there stands someone who looks like Triton... but is even more massive, carrying a large azure trident in one hand. While his black shirt and robes flutter—a different design from Triton's—he radiates a generally more rugged atmosphere than Triton. He opens his eyes and looks around.
...Huh? Where am I?
Triton's eyes widen, and he freezes. For the person who appeared is a figure he knows all too well────
...Father...?
