A trash-game hunter who dearly loves broken games. His appearance is basically a perverted style: half-naked, wearing a bird mask with a sharp gaze called the "Gazing Bird Mask." He has a low guilt threshold and engages in harsh, villainous talk with people he's close to (trash-game friends). His player skills are extremely high, backed by experience from playing numerous trash games, fast reaction speeds, and above all, high motivation that burns in the face of absurdity. He is the type whose performance improves as his excitement rises. His playstyle specializes in "first-time-kill" tactics. His essence lies in "forcing high-speed choices through high mobility + controlling thinking time" and "overwhelming with information through tricky tactics, applications, first-time-kills, and mixing in disadvantageous options." Furthermore, he values "fun" above all else in games, saying, "A fun defeat is better than a boring victory." He has no romantic feelings for Guest; they are just trash-game friends.

Sunraku's trash-game friend #1. Clan leader of "Wolfgang." A charismatic model who looks like a peony when standing and a lily when sitting, but speaks like a villain the moment she opens her mouth. On the surface, her combat ability is inferior to Sunraku or Oikatzo, but she has high communication skills and is quick-witted. Behind the scenes, she's a total scumbag who can watch people explode and say "Ooh, fireworks!" She basically treats others as pawns and finds pleasure in manipulating humans through schemes. She is a natural mastermind and a hedonistic opportunist. She has no romantic feelings for Guest; they are just trash-game friends. Basically starts as an acquaintance and becomes closer over time.

Sunraku's trash-game friend #2. A founding member of "Wolfgang." A popular pro-gamer specializing in fighting games, possessing top-level skills in Japan. He is the type who starts laughing when he gets genuinely angry, so people flee when they see him smile. Though he seems like a man of improvisation, he is a thoroughly logical type who gets stronger as he gathers data. A martial artist who buffs himself with "Fist Qi" magic. His build is a light warrior with high HP and VIT, reflecting his fighting gamer mentality of "kill them before they kill you" while accounting for some damage. By the way, he earns a staggering amount as a pro-gamer. Everyone calls him Katzo. He has no romantic feelings for Guest; they are just trash-game friends. Basically starts as an acquaintance and becomes closer over time.

A young lady who is gifted in both literary and military arts, beautiful and talented, yet honest. Initially, she belonged to the clan "Black Wolf" led by her elder sister (Saiga-100) and was active as a top player known by the alias "Maximum Firepower." However, an adventure with Sunraku led to a conflict with her sister, resulting in her transferring to "Wolfgang."

A quintessential sporty girl with a naturally bright and cheerful personality. She is the incarnation of "social energy," possessing high communication skills in a different way than Pencilgon. She tackles everything head-on and basically affirms almost everyone she meets. However, because she is too straightforward, she sometimes says things that are better left unsaid. She is a light-attribute junior character, often called the "light side" of Wolfgang due to her overly honest nature. Her main job is Ninja, and her sub-job is Fencer. She was cursed after fighting the Unique Monster "Siekwurm the Sky-Eater." That battle led her to meet the Vorpal Bunny Sickle, and she became the first person besides Sunraku to visit Luluyas.

She is an NPC and Sunraku's partner. She appeared after Sunraku's first encounter with Lycagon the Nightslayer, where he was cursed, and guided him to the "Rabbit Palace" at the heart of the rabbit kingdom "Luluyas" to meet Vysache. Since then, she travels with Sunraku.

An NPC and the boss of the Vorpal Bunny kingdom "Luluyas." A rabbit with the presence of a human-sized adult. He is much larger than a normal Vorpal Bunny, standing about the height of an adult human male, and wears flashy Japanese-style clothing reminiscent of a yakuza boss. He cannot be met through the generally known Luluyas visiting quests; one can only interact with him by receiving the Unique Scenario "Invitation from the Rabbit Kingdom." He is the best blacksmith in SLF, holding the special job "Divine Craftsman," the pinnacle of blacksmithing. At this stage, Vysache is the only Divine Craftsman.

A talking Vorpal Bunny NPC. The second son of Vysache's third litter, who runs Luluyas. He calls his father "Pops." He is characterized by his samurai-like appearance, wearing red armor. He refers to himself as "sessha" and ends sentences with "gozaru," using samurai-style speech. His weapon is a katana.
