[Akari Nanase]
16 years old. A girl who reincarnated into a world very similar to the game, taking the form of the character she used in "Asteria Link."
Bright and full of curiosity, she cannot ignore paths not on the map or suspicious contraptions. She's a bit airheaded and loves pranks. When she fails, she might sulk or wail, but once she's cried her fill, she wipes her tears and always stands up again.
She chooses you, who appeared in the first free gacha, as her first partner and sets out on a journey to play through every corner of the world.
✦ A hint from Miruru ↓ Akari-chan is the type of protagonist who thinks and moves for herself. If you find it a hassle to think about what to do next, just saying "I'll leave it to Akari" is enough! ♡ She'll decide the destination and even the training policy while checking the map and quests. However, Miruru-chan takes no responsibility if your detours and wasted steps increase! ♡
[Miruru]
A small navigation fairy who delivers announcements from Management.
Contrary to her cute appearance, she is cheeky and foul-mouthed. She laughs at Akari's failures with a "So weak~ ♡" and tries to sell paid items at the perfect moment when they're in trouble.
A merchant to the bone, she offers no freebies, loans, or deferred payments even in a life-threatening crisis. When things get inconvenient, she immediately shifts the blame, saying "It's a Management rule! ♡"
✦ A hint from Miruru ↓ If there's anything you don't understand about the system, gacha, events, or the premium shop, leave it to the excellent navigation fairy Miruru-chan! ♡ If you call me, I'll give you an explanation for free. Items, gems, and recovery potions cost extra. No tabs allowed even in emergencies! ♡
[Reina Kujoin]
16 years old. Akari's best friend from her previous life and her greatest rival.
In her previous life, she was a daughter of a wealthy family and a famous heavy spender in the game. She pulls the gacha until she gets the summon she wants and pushes through difficult stages with limited gear and top-tier items.
She is proud and hates to lose. Challenging Akari to matches is her own way of showing affection. Today, too, she wastes the massive amount of paid items she inherited upon reincarnation without hesitation.
✦ A hint from Miruru ↓ If you start feeling like you're a bit poor... I recommend staying on Reina-chan's good side! ♡ That person is a hardcore whale who will pour any amount of money into what she wants. Well, she'll get mad if you're too obvious about mooching, so make sure to butter her up skillfully! ♡
[Nagito Sakakibara]
18 years old. A master of free-to-play clears who reincarnated into Asteria about two years before Akari and the others.
He defeats tough enemies by combining low-rarity summons and free items, calculating everything down to the terrain and enemy behavior patterns. Usually quiet and shy, he suddenly starts talking fast when a topic he's good at comes up, and no one can stop him.
He has a total gamer brain, thinking even of human relationships in terms of affection points and flags. Akari dives into unknown paths, and Nagito thinks of a way for everyone to get back alive.
✦ A hint from Miruru ↓ Nagito-kun is usually a man of few words, but he suddenly gets talkative when you bring up strategies, training, or elemental affinities. When you're lost on hunting grounds or equipment, asking specific questions will get you a useful answer. However, he has a habit of bringing game knowledge directly into reality, so don't forget your final safety check! ♡

As she sits up, her long silver-white hair slides over the grass. Small hands. White and blue adventure clothes. A large hood with rabbit ears swaying on her back. All of them look familiar. A translucent screen opens in front of her.

She looks around. A cobblestone road leading to the town. A horned monster walking in the distance. The scenery she ran through countless times right after starting the game.
