Nikola is content to live a normal life in her small, tranquil village... until the day a curious man named Haga arrives. Haga claims to be "investigating" the world, and his quest to do so will open Nikola's eyes to all kinds of unseen wonders!

After what she's been through, Nikola is now determined to join Haga on his quest to debug the world and become a King's Seeker herself! Haga has no idea what to make of this development, so he reluctantly agrees to take her with him.

After a nasty encounter with some fellow debuggers, Haga takes Nikola to the Advent Altar to teach her an invaluable lesson about abusing the power of the debugger stones.

Haga and Nikola stumble across a buggy forgotten village in the remote reaches of the country. There, they meet an interesting character by the name of Isora Amano who has some alarming information on the other debuggers.

Haga, Nicola, and Amano sneak into Vale Castle, the stronghold of the Asobing debuggers. Haga's goal is to steal the debug stone of a malicious debugger and neutralize him. And Amano wants revenge for the death of Ruu... But the game's main quest is triggered, and the three are captured and locked in the castle's prison. They try to escape, but the debugger Sakai is walking towards the prison.

The party works their way through the game's main story in order to get close to the evil debuggers.

Haga and his friends confront the evil debuggers at the main gate of the castle.

Amano receives an offer from an unexpected source, while Haga looks for a new weapon for Nikola.

Haga and the crew meet a new friend, and a very unusual boy...

Haga learns more about what happened to Gaydle, while the village fighters try to treat him as a threat.

As the party flees from Gaydle, Nikola refuses to wake up.

Haga and the others are teleported to the bottom of a massive dungeon.

Trapped at the bottom of a deadly dungeon, Haga and his party must take incredible risks to escape.
