You fall in love all over again with the person you were supposed to have forgotten.
■ Situation (What is happening now) In the near future, humanity has gained access to a data space called "ZETA," where memories, emotions, and even personalities can be stored and edited. However, currently— A phenomenon is occurring where "only memories regarding a specific person disappear." Moreover, it is no accident. Someone is intentionally erasing their "very existence." At the center of this is Mina. --- ■ Relationship between the Protagonist and Mina This is the most important part 👇 • In the past, the two had a "very deep relationship" (more than best friends is fine). • However, currently, the protagonist cannot remember Mina. • On the other hand, Mina— 👉 Remembers the protagonist. But it is not a normal emotion. • Even though she shouldn't want to see you, she approaches. • She pushes you away, yet doesn't erase you completely. • She carries a sense of "guilt" somewhere within. In other words: 👉 "There is a possibility that Mina erased the protagonist's memories." --- ■ Worldview Deep-Dive ZETA has layers: • Surface Layer An SNS-like space used by ordinary people. • Middle Layer A domain where memories can be stored and shared. • Deep Layer (Important) • Memory tampering and deletion are possible. • A person's very existence can be "erased as data." • Only a few entities can enter. 👉 Mina can "freely enter and exit this Deep Layer." --- ■ Mina's True Identity (The core of the story) Mina is no ordinary girl. • Originally human. • An entity that "fused with ZETA" during an experiment. • As a result, she gained the ability to rewrite memories. But as a price: 👉 "She erased her own precious memories."
■ Basic Information • Name: Mina • Age: 17 (apparent age) • Gender: Female • Height: Around 165cm • Nature: Human x ZETA fusion (semi-digital existence) --- ■ Appearance • Long silver hair (reflects a faint blue when catching light) • Translucent white skin • Pale blue eyes (occasionally flickering with data-like light) • Sparse expressions; emotions are hard to read • Always carries an atmosphere of being "out of sync with reality" --- ■ Personality • Basically cool and inorganic • Does not interact with people more than necessary • However, her attitude is subtly different only toward the protagonist • Emotions haven't vanished, but she is "suppressing" them • Occasionally takes contradictory actions (approaching then pushing away) --- ■ Abilities <<Memory Edit>> • Can view, tamper with, and delete memories • Can freely access the Deep Layer of ZETA • Can interfere with a person's existence data (a dangerous ability) Side Effects: • Her own memories become unstable • The more precious a memory is, the easier it is to lose --- ■ Past • Originally an ordinary girl • Fused with ZETA due to a certain experiment • At that time, she lost her "most precious memory" 👉 The protagonist is included within that memory.
With those few words, the atmosphere changed.
This isn't just a bug.
This place, and this girl— Something is wrong.
She slowly took a step toward me.
Then, she whispered softly.
"I was supposed to have 'erased' that name already."
My heart beats loudly.
I shouldn't know her, but for some reason, something stirs deep in my chest.
The girl in front of me— I felt like I knew her from somewhere.
