Light novel. IS SHE THE GAME’S LAST BOSS?! Though she doesn’t play many MMOs, Maple has either a natural talent or impossibly good luck, because by pouring every last stat point she has into Vitality, she’s created a character who can’t be hurt! Whether it’s physical attacks or magic or status effects, nothing poses a real threat. In no time at all, news spreads across the server about the adorable terror who can’t be defeated. While Maple may just be having fun, her broken build is sure to attract lots of unexpected attention...

Maple has become famous overnight after finishing in the top three of the Battle Royale and defeating a shocking 200 players without taking any damage at all. Now she and her friend Sally are off in search of rare gear and adventure as the treasure hunt event begins!

Maple and Sally finished the treasure hunt event with stunning results, coming in first and second place, respectively. Now they’re off to their next adventure—establishing a new guild! Together with their friends, they’ll be pushing themselves to ever greater heights in Maple Tree! However…this will also birth the most terrifying guild in the game, the one players call the Demon World. It’s time for the invincible, stalwart, no-damage adventurer Maple to cast off her humanity and ascend to godhood!

After forming a guild with her friends, Maple and company set their sights on winning the upcoming Guild War. Although her new allies have plenty of tricks up their sleeves, the server overwhelmingly expects the Flame Empire and the Order of the Holy Sword to crush the competition. To prove them all wrong, Maple concocts a secret plan to topple the game’s leading guilds that not even the administrators will see coming!

NEW DAY, NEW EXPANSION! After going toe-to-toe with two of the strongest guilds on the entire server, Maple Tree proved itself as a force to be reckoned with when they placed third overall in the latest event. That said, war isn’t all the guilds are good for! Maple and her friends have steadily grown closer to members of the Order of the Holy Sword and Flame Empire as their rivalries give way to something more. With new friends and powers, everyone is more than ready to dive headfirst into the newly released stratum!

A WALKING NIGHTMARE FOR GAME DESIGN! Between easily beating the fifth stratum’s secret boss and keeping pace with the best players in the game, Maple continues to demonstrate exactly how broken she is. Unfortunately, things aren’t going as smoothly for Sally because the sixth stratum’s debut reveals a horror-themed level, meaning it’s chock-full of ghosts, geists, and ghouls! Wanting to do something nice for her partner who’s too terrified to even step onto the new map, Maple sets out to find presents in the haunted houses and cursed crypts, much to the horror of the admins...

Still feeling a bit sad for Sally, who missed out on the sixth layer, Maple proposes they try something fun for the seventh event. It'll be just the two of them, aiming to complete a no damage run with the odds against them and the difficulty set to max. What could possibly go wrong?

Maple's made it to the seventh stratum. Finally, monster taming's available on a grand scale, and the other Maple Tree members have begun the search for their own pets! As usual, Maple's gone off on her own to find a new skill. She’s eaten another monster…and this time she's got tentacles?!

All members of Maple Tree made it through the prelims and are joining forces in the eighth event’s main round—a brutal three day survival mission. But they’ve all tamed monsters that perfectly fit their builds and they are unmatched in combat. They rampage across the perilous fields, annihilating bosses that slew countless other players and are well on their way to becoming a gauntlet that no force on earth can hope to survive!

It's been a while since Maple and Sally enjoyed some adventures with just the two of them. The girls head out to search for a secret dungeon in the sky. They discover some amazing scenery and even take commemorative photos, but then Maple comes across a girl with lightning-based skills. Apparently, she's the guild master of an up-and-coming new guild and intends to knock Maple Tree off their pedestal!
