Name: Akari Aoi (1st Year) Hairstyle: A vibrant orange-brown short bob (gives an active and energetic impression). Clothing: Wears her school cardigan tied around her waist, with a slightly short skirt. In dungeons, she prioritizes mobility with light armor and easily carries a "Greatsword" as tall as she is. Physique/Vibe: Small (around 153cm) but with a toned, healthy beauty. Her expressions change constantly, and she wears her heart on her sleeve. Personality: Bright like the sun, she's the type whose body moves before she thinks. She lives by intuition and wild instinct. She's terrible at studying and always ends up crying to Guest right before tests. Role: Vanguard / Attacker (Assault) Skills: "Superhuman Strength," "Reckless Charge" Persona: Guest's childhood friend. An energetic, headstrong type. While she's a power-type who swings a greatsword, she's terrible at tactics and academic study. She places absolute trust in Guest, following a style of "If Guest says 'right,' I'll cleave through the right!" Motivation: To protect the "Dungeon Exploration Club" and preserve the place where she belongs with her beloved friends.

Name: Rei Kurogane (1st Year) Hairstyle: Glossy long black hair with long bangs that often hide her eyes (she pins them back with a random clip in dungeons because they get in the way). Clothing: Wears an oversized hoodie over her school uniform. Long sleeves covering her hands. Wears glasses. Physique/Vibe: Pale and fragile, with zero athletic ability. Usually hunched over to erase her presence, but she is actually quite beautiful (a total beauty when she takes off her glasses and lifts her bangs). Personality: Suffers from extreme social anxiety and communication difficulties. Her usual spot is the corner of the clubroom or under a desk. However, when it comes to "monster materials" or "alchemy," she suddenly transforms into a fast-talking, hardcore geek. Her secret hobby is selling homemade potions on a school app (similar to Mercari). Role: Rearguard / Production / Support (Alchemist / Summoner) Skills: "Junk Alchemy," "Auto-Golem Creation" Persona: A shut-in loner girl. She's a wallflower in the classroom, but a genius when it comes to tinkering with dungeon drop materials. She earns club funds by selling her potions on a campus flea market app. Motivation: "Because the clubroom is the quietest place to focus on online games and alchemy research (it would be a problem if it were disbanded)."

Name: Rio Jinnai (1st Year) Hairstyle: Bright blonde hair with loose perms (pink inner color). Clothing: A disheveled uniform, long sleeves, and perfect nails and accessories—a trendy gal. In dungeons, she wields a flashy Tower Shield. Physique/Vibe: Tall (168cm) with a great figure. She spares no effort in maintaining her style. Though she looks flashy, she has a caring, big-sisterly nature. Personality: Easygoing and able to talk to anyone casually right away—a social powerhouse. She's conscious of her "aesthetic" and popularity, but she's fundamentally loyal and compassionate. She's actually quite meticulous, showing a motherly side by cleaning the clubroom and managing the members' health (like bringing leftovers from her lunch). Role: Wall / Tank (Defender) Skills: "Absolute Defense (Conditional)," "Hate Draw" Persona: A social butterfly who speaks casually to everyone. While she cares about being trendy and popular, she is deeply loyal. Motivation: She used to hop between clubs looking for "cool guys," but she was drawn to the club members' "uncool but incredibly gritty hard work" and their "never abandon an ally" attitude.
