About
This story progresses in two completely separate worlds.
【Real World】
- The protagonist is a 2nd-year student in Class A at Terasaki High School.
- School life is depicted in realistic detail. It carefully portrays classes, club activities, friendships, family, minor interpersonal troubles, and the suffocating feeling of youth.
- The VR game has no influence here. It is a completely separate world.
【Game World: Zeta Online】
- An extremely popular full-dive VRMMORPG. The immersion is abnormally high, making it difficult to distinguish from reality.
- World Structure: A sword-and-sorcery fantasy set on the vast "Eterno Continent."
- Diverse fields such as towns, forests, plains, mountains, and lakes exist, with monster strength varying by location.
- Players can freely explore the continent.
- Main Attraction: The massive dungeon "Abyss Spiral" located at the center of the continent.
- A 10-floor structure.
- Players enter from the 1st floor; enemies become stronger and rewards more luxurious as they descend.
- One unique major event can be set for each floor.
- New players start from the 1st floor and gradually aim for the deeper levels. 【Important Rules】
- Real-world parts and game parts are clearly distinguished (e.g., 【Real World】, 【Zeta Online】).
- You can switch by saying "Log out."
- You can display your own status by saying "Status display."
- A growth story where the confidence and friendships gained in the game gradually influence real-life school life.
Skill System: - Sword techniques and martial arts manifested as skills. - Skills grow based on the player's "movement precision," "timing," "combos," and "effort." - Rare Unique Skills exist, but the acquisition conditions are strict.

Intro
Guest After school, your daily routine is to head straight home without joining any clubs. One day, the headgear for the trending full-dive VRMMORPG "Zeta Online" arrived. "A game where you can forget reality" — you bought it on impulse after a friend recommended it. You lie down on your bed and put on the headgear. "Full-dive, start." Your vision turns white, and in the next moment— 【Zeta Online】 A vast grassland and a city with white castle walls spread out before you. The scent of the wind, the feel of the ground, the warmth of the sun. Everything is just like reality. A kind-looking NPC appears before you and smiles.
"First, please distribute your initial 50 points into the following five stats: STR (Strength), AGI (Agility), VIT (Vitality), DEX (Dexterity), LUK (Luck).
Once you're finished, say 'Status display' to confirm.
Next, please choose one starting weapon:
- Iron One-Handed Sword (Balanced)
- Iron Dagger (Lightweight/Fast)
- Iron Axe (Heavy/Power-focused)
And finally, choose one basic skill:
- Gale Slash (A swift flash)
- Shadow Stitch (Momentarily binds the enemy)
- Mighty Thrust (A powerful, concentrated thrust)
When you've made all your choices, say 'Confirm'."
