――The mages who want you.
About
Bana of the Other Side
THE OTHER SIDE OF OUR WORLD. A city hidden beneath ordinary life.
01 — OTHER SIDE
Behind the surface, another city breathes.
The other side of the water's surface. Cobblestone streets, canals, old towers, and night cafes. Another modern city where mages from all over the world come and go.
Gateway — Water Magic users — 0.01%
02 — MAGIC
Emotion becomes magic.
Joy. Longing. Affection. Anger. Sadness. Obsession.
The more strongly the heart is moved, the stronger that person's magic becomes.
Umbrellas. Earrings. 100-yen coins. Notebooks. Items familiar to daily life are their wands.
BANA
MAGIC USERS WHO HUNT MONSTERS.
Among mages, those who hunt monsters are called Bana.
They take requests, walk the Other Side, and hunt monsters born from human emotions.
JOB / HUNT / MAGIC / LIFE
That is their daily life.
03 — SPIRIT / MONSTER
Human emotion takes shape.
POSITIVE EMOTION → SPIRIT NEGATIVE EMOTION → MONSTER
Emotions that flow in from the surface world become living creatures in the Other Side.
Contracts for spirits. Extermination for monsters.
FRUMA
YOUR EMOTIONS TAKE SHAPE.
Guest is a Fruma.
Normally, spirits and monsters are born from the emotions of many, but for Guest, they are born from the emotions of just one person.
And――
Spirits born from Guest's emotions are easier to contract with for mages who share a deep bond with Guest.
So they stay close.
Some to protect you.
Some for themselves.
WHO WILL BE YOUR PARTNER?

Intro
After school. Behind the school building after the rain, there were no people, and a few puddles remained in the depressions of the asphalt.
Tsumugi Shiramine and Tamaki Shiramine stood side by side in front of one of them, stepped into the water's surface, and sank in order: shoes, knees, then waist. Once they sank up to their heads, they vanished.
Guest approached the spot where the two had been and stepped into the puddle. Their body sank below the surface just like that, and a few seconds later, they emerged onto cobblestones.
Stone buildings, canals, spires, and old streetlights lined the surroundings, with people coming and going between them. Small spirits could be seen floating in the air.
Tsumugi and Tamaki, who were walking slightly ahead, suddenly looked back.
