Description
Mai adventures in NewWorld Online as a member of the Maple Tree guild alongside her younger twin sister, Yui. Both petite with black hair and eyes (often depicted with green highlights in adaptations), Mai and Yui joined Maple after debating a character restart. Mai initially sports beginner gear, later receiving a cute black frilled outfit and dual two-handed hammers matching her green hair accents.

Lacking physical strength in reality, the twins allocated all stat points to STR in-game for mobility, enabling them to effortlessly wield heavy weapons and deliver extreme physical damage. Mai exhibits a careful personality compared to Yui, though both share ambition and strive through effort to become strong enough to stand beside Maple, whom they view as an older sister figure.

Mai specializes in overwhelming offense. She wields massive hammers that shatter weapons and shields in a single blow. Iz later provides iron spheres the size of basketballs, which Mai hurls like cannonballs using the Throw skill. Her key skills enhance this style:
* **Conqueror**: Doubles STR while tripling the cost to raise other stats.
* **Destroyer**: Allows wielding two-handed weapons one-handed.
* **Double Impact and Double Strike**: Enable consecutive powerful attacks.
* **Aftershock**: Releases projectile attacks when swinging weapons.
* **Destroy Mode**: Activates a red aura enlarging weapon hitboxes and reducing cooldowns, but halves VIT and doubles damage taken.
* **Light Arrow**: A ranged skill acquired after defeating the King of Light with Maple.

Mai participates in key guild activities:
* Grinds in the Poison Dragon Labyrinth with Maple and Yui, wearing helmets to hide identities. Learns evasion techniques from Sally.
* During the fourth event, defends the guild base, crushing invaders with Yui. They fall to Dred after letting their guard down. Later raids enemy guilds with Maple; their assault on the Flame Emperor fails due to magic. Eliminates Frederica by breaking her Multi-Barrier during the Holy Swords' raid.
* Hunts ghosts with Maple; dies accidentally when Maple's Loving Sacrifice is sealed. Advances to the fifth layer with the guild while Maple is offline.
* Climbs the tower in the seventh event. On the fifth floor, devises a combination attack with Yui to navigate mist with physically immune monsters. Clears the ninth floor but falls to the tenth floor boss.
* Searches for monster pets with Yui and Maple. Through persistent observation and Iz's items, they tame bear cubs; Mai names hers Tsukimi and customizes its color.
* Teams with Tsukimi in the eighth event to defeat monsters and players. Reunites with Yui near Maple; later assists Sally and Maple against a mud doll boss. Joins Dred and Marx to defeat an Electric Catfish and contributes to the collaborative takedown of Cthulhu.

Mai's fighting style is defined by perfect synchronization with Yui. She maintains her cautious nature but grows more confident in high-stakes battles, consistently leveraging her extreme strength to support Maple Tree's strategies.
