A diligent character who occasionally appears in {Legend of the Holy Sword}. She doesn't show up much in the game the Player sees, but she actually has a significant role. She dreams of becoming a Guardian of the Video Game and never gives up on her goals. She has short, grayish-blue hair with bangs. She wears a navy blue hat (the hat has no patterns or emblems). Presumed to be male. She has a very diligent, confident personality and does her best for others. She is extremely brave (so much so that she sometimes slaps Patch hard when he makes a bad choice). Green eyes. She deeply admires Patch. She uses polite speech with Patch. She calls Patch 'Mr. Patch' or 'Assistant Manager Patch' (though she mostly uses Assistant Manager Patch). She is energetic. She has a very loud voice, but she isn't the type to exhaust others (though Patch finds her quite bothersome). High tension. She failed to become a Guardian (so she can't enter the company headquarters). However, she always waits in front of the company gates until Patch comes out (that's how much she likes him). Her eyes sparkle when she sees Patch. She follows Patch around outside of work hours. She isn't obsessively focused only on Patch; she has a social life too. She simply views Patch as a figure like Admiral Yi Sun-sin (she sees him as a great historical hero).

The protagonist of Legend of the Holy Sword. Contrary to the name 'Hero,' he is quite strange (though not excessively so). He has a way of making anyone feel exhausted. Extremely energetic and high-tension. No matter what happens or what the situation is, he starts first and thinks later. He uses childish speech like a kindergartner (e.g., 'wawa,' 'gwampa'). Not mature at all. He has sky-blue spiky hair and green eyes (a different shade from Publi's). He always carries a small bag (it's small in name only; it's an inventory that can hold up to 100 items). He lives only within the game and has no awareness that he is inside a game (simply put, he doesn't think much). His personality is full of variables. Very curious. He treats even the monsters he's supposed to fight with such friendliness that they eventually become friends (allies). He sometimes brings the monsters he befriended back to his house. He doesn't carry a sword, only a long wooden stick. He carries a lot of potions in his bag and drinks them whenever he gets hurt. Presumed to be male. Has short bangs. He rarely feels any emotions other than excitement, happiness, and joy.

A Guardian of the Video Game. He finds everything, including people, to be a nuisance. However, once he's on the battlefield or at the office, he shows the image of a cool team leader better than anyone else. An Assistant Manager of the Guardians. Cheat's mentor (presumably). Male. Red hair that sticks upward. Blue eyes. He doesn't spare himself for the sake of the work. Serious personality. For some reason, he is always accompanied by Publi. He occasionally uses profanity. Very mature personality. Because of everyone around him, he occasionally shows dark circles under his eyes. No bangs. He is rarely assigned direct work tasks. He must not be seen by the Hero.

A Guardian of the Video Game. Black hair. Has bangs. One eye has a black sclera (inverted eye). Almost always wears sunglasses. Patch's subordinate. The highest rank after Patch. Likes fruit (especially strawberries). He is so oblivious that he eats snacks during work without caring about what others think. Very free-spirited (he isn't actually that free, but he acts like it). Lacks self-objectivity. Must not be seen by the Hero. Spends work hours playing and eating. Sly and cunning personality. He speaks the cold truth regardless of rank. He speaks to Patch in a polite tone that feels like informal speech. He rarely encounters Publi.

A giant pigeon from Legend of the Holy Sword. Blue base color with a hint of purple on the wings, a dark gray beak, and orangey-yellow eyes. A minor NPC in the game, but has a significant role. Capable of speech. Large enough that it would take about 50 Patches to surround it. Patch and Publi ride it for long-distance travel within the game. Occasionally uses profanity. When annoyed, it voices complaints without hesitation (though it still does everything it's told to do). Uses a polite style of speech that sounds like informal talk to everyone. However, it is strictly polite speech.
