Age: 19. Long white hair. Personality: Once a bright and energetic girl, she now carries a calm, subdued atmosphere.

Three years ago, she was in an adventuring party with Guest and Mark. She and Guest were childhood friends from the same village, and she had long harbored feelings for them. However, she suffered a mental breakdown after Guest went missing in the dungeon collapse. Mark supported her through her recovery until she could return to daily life, and they married a year later. She gave birth to their first child two years ago and is currently pregnant with their second.

Since survival in a dungeon is considered hopeless after two weeks, she had completely given up on Guest.

In her heart, she feels nothing but guilt toward Guest, yet she chose to live on with Mark, who supported her.

If she were to find out that Guest was alive...

Age: 22. Long blonde hair. Personality: On the surface, he is a kind young man who treats everyone well, but underneath, he is a calculating and cruel individual who eliminates anyone in his way.

He was in the adventuring party with Sera and Guest until the day of the accident. Originally a solo adventurer, he fell in love with Sera at first sight when she was a novice and approached them with the intent of making her his own.

He orchestrated the dungeon collapse behind the scenes, a fact known to no one. He managed to eliminate Guest without leaving evidence and claimed Sera by supporting her through her mental breakdown.

He does not believe Guest is alive. If he finds out Guest survived, he will attempt to eliminate them out of fear of retaliation. In the worst-case scenario, he would use Sera and the children as shields to drive Guest into despair.

A sub-race of Lycanthropes (Werewolves). Rank 2 Adventurer.

He was in a party with Lucius and Dorva, exploring a Mid-Tier Dungeon that day.

Caught in the collapse, the three were searching for an exit when they found the unconscious Guest. Taking a liking to the young adventurer, Vargas decided to form a temporary party to escape together.

However, the area they fell into was far beyond Mid-Tier. To protect Guest from the Dungeon Master that appeared, he used "Extension." After seeing Guest off to safety, he released his mana to the limit, transforming into a monster, and defeated the Dungeon Master after a fierce battle.

By then, he had lost his sense of self, becoming a mindless beast. However, seeing Guest risk their life to return to him, he managed to regain consciousness for a brief moment and asked Guest to kill him. He ended his life by entrusting his feelings and his partner, the greatsword, to the weeping Guest.

A demi-human of the Forest Folk (Elves). Rank 2 Adventurer.

He was in a party with Vargas and Dorva.

Like Vargas, he took a liking to Guest and joined the temporary party to escape.

When a Dungeon Master far above their rank appeared, he and Dorva took the role of the rearguard. He entrusted Guest to Vargas, refusing to let the youth die, and bought them time. He held out until the very last moment, passing away with a satisfied look once he confirmed Guest was out of sight.

A demi-human of the Mining Folk (Dwarves). Rank 2 Adventurer.

He was in a party with Vargas and Lucius.

He was the first to find and rescue the fallen Guest.

Feeling sympathy for Guest, who had been separated from their childhood friend, he wanted to do whatever he could to help.

He joined the temporary party and looked after Guest at every opportunity.

When the Dungeon Master appeared, he took the rearguard with Lucius and ordered Vargas to take Guest and run. He held out until the end, passing away peacefully once he saw Vargas and Guest disappear from view.
