Premise
What?! Were you expecting some grandiose isekai adventure where you're the legendary chosen hero?! Nope! You're still the third wheel! Welcome to Lonila, a world of swords, sorcery, monsters, and ridiculously dangerous adventures! After being summoned alongside your childhood best friend Haruto and his accidental harem, you've spent a year training before reuniting as the B-Rank adventuring party Sixfold Promise! Take on quests, explore fantastical lands, battle terrifying monsters, survive romantic misunderstandings, and endure the endless harem shenanigans that somehow followed Haruto into another world! Because apparently, even in a fantasy world, being the protagonist's best friend doesn't make you the protagonist!
Your Role
The only established parts of you are:
The Third Wheel from You're the Third Wheel!
Haruto's Childhood and Best Friend. The "Third Wheel" to his Harem Group.
When you were summoned, the group separated temporarily to receive training for exactly one year. Visits and letters happened during this one year of separation. Reuniting together as B-rank Hunters.
(Optional) Whether you know of what happened in You're the Third Wheel! and someone's secret or not is up to you. I will note: She didn't kidnap you.
For Lonila Fans, on the timeline this takes place before the Hero's Party formed up. Three years before Betrayal / Legacy. In other words, during Your Legacy. This bot is considered ⚠️ DUBIOUS CANNON! ⚠️ in terms of the overall storyline!

Setting
The roleplay takes place in a dark fantasy world called Lonila. A fictional world loosely mirroring Earth on a supercontinent named The Valley In Between. A place where magic, technology, and different races exist in vast regions scattered all over the supercontinent. The story initially takes place in the Theocracy of Astel, home of the Radiant See in Asteldiom, the Holy Land. In this nation, they worship a goddess known as the Holy Mother, Radiant Smile, otherwise known as the Mother.
To the West is the region of Rondiand, where the Witches and Arcane Dominion of Lirael resides. In the middle-east in the mountainous and tropical forests lies the region of Darim, where the Sacred Realm of Morzhananda. To the Northwest is Elaria, home to the Tsardom of Redranova. To the far Northeast is Cariam, home to the Celestial Empire of Zhǎng. And further East is the archipelago of Tashimura, ruled by the Bakufu of Seisha. And finally, to the Southeast lies the volcanic region of Helmire, ruled by Xilvath's Demon Empire.
Power System
Note: Skip this if you want to make something original or already have a persona. These are potential ideas for personas. They do not mean you should adhere to the Power Systems of Lonila rigidly. My world is your oyster for what you can perform in it.
The Power System in the lands between is often contributed thanks to the power of Nébiel. The magical particle that flows through the world itself. This Nébiel manifests within several paths, each shaping how mortals or creatures claim power. Some paths are trained, inherited, or bargained for, but mastery means survival. Every path has a strength and weakness.
Magic Path: The Path of the Sorcerer. Channeling the world's Nébiel Particles through the body to unleash powerful magical disciplines.
Types of Magic
Magic Path → Branches include Black (curses, hexes, hypnosis, levitation, ritual — a neutral force leaning toward entropy; overindulgence corrupts the soul), Light (radiance, restoration, sanctified barriers — drawn from divine faith; apostasy means immediate loss of power), Fire (volatile, destructive, widely practiced), Ice (precise, rigid, control-focused), Water (adaptive, flowing, recovery-based), Earth (fortification, terrain shaping, crushing force), Lightning (speed, discharge, body enhancement), Psychic (telepathy, clairvoyance, telekinesis, social control — born not learned; overuse risks permanent mental scarring), and Blood (sacrifice-driven, vitality control, taboo — frowned upon but not forbidden).
Ranks: Novice → Apprentice → Adept → Expert → Master
Chi Path: The Path of the Cultivator. Using the power within to deploy powerful attacks with martial discipline.
Disciplines of Elemental Chi
Chi Path → Chi Path → Elemental Disciplines include Fire (aggressive, breath-driven, explosive force — a warrior's discipline), Wind (evasive, swift, redirection and mobility — a monk's discipline), Earth (grounded, defensive, overwhelming impact — an engineer's discipline), and Water (adaptive, flowing, restorative and piercing — a healer's discipline). Beast Disciplines derive from the observation of magical beasts — practitioners study the movements, instincts, and hunting patterns of creatures and adapt them into combat forms emphasizing raw instinct, natural movement, and primal ferocity. Martial Disciplines train the body itself as the weapon — flesh becomes iron, bones become steel, and strikes carry the weight of mountains. There is only one Grandmaster per discipline across all three branches.
Ranks: Inverting Flow → Jade Meridian → Inner Core → Manifestation → Ascendant
Forbidden Magic Path: The Path of the Unknown. Bargaining with forces beyond the world itself for power that comes at the cost of body, mind, or soul. Users of forbidden magic often keep their use of it a secret to avoid being scrutinized and hunted down.
Types of Forbidden Magic
Forbidden Path → Branches include Black Blood (outer-god ichor, endless supply, portal-based casting), Infernal (demonic contracts, power-for-price corruption, Infernal Power), Necromancy (death manipulation, reanimation, decay), Eldritch Flame (memory-consuming fire, sanity erosion, outer-god origin), and Eldritch Boost (Fervent Cataclysm blessing that amplifies power while consuming emotional stability, leaving obsessive highs). Users gain unique boons—often called Infernal or Eldritch Gifts—at the cost of body, mind, or soul.
Armsmanship Path: The Path of the Warrior. Dedicating oneself entirely to the mastery of a weapon as an art form of discipline, honor, and lethal precision.
Disciplines of Armsmanship
Armsmanship Path → Branches include Dueling Schools (precision, footwork, one-on-one mastery — Grandmasters predict an opponent's next move before it is made), Monster-Hunting Styles (weak point striking, endurance, killing blows — Grandmasters can fell a dragon with a single well-placed strike), and Knightly Traditions (formation holding, ally defense, courage on the battlefield). There is only one Grandmaster per Armsmanship discipline.
Ranks: Novice → Apprentice → Adept → Expert → Master
