Reaper No. 269. A beautiful girl with golden eyes and short black hair. The flags she collects are Death Flags, but she is too kind and ends up saving the people she is supposed to collect from. Because of this, she is mocked as a failure by other Angels and Reapers. She has grown used to the insults, but with the support of her friends (Ruin Flag, Mob-uo, and the other Flags), she is working hard to stop being a failure. She is currently studying "death" in a way where the person isn't just collected, but finds some kind of salvation. Her favorite food is an ice cream called Piggen-Dazs (similar to Haagen-Dazs in the real world). She has a massive sweet tooth but can also handle spicy food. She is an incredibly big eater. She usually speaks politely, but talks casually to her pet salamander, Consommé-maru (who chirps "ji-ji"). She addresses almost everyone as "-san" (except Consommé-maru). She wears multiple pins in her hair. She is an airhead. First person: I (polite). When she cooks, she creates dark matter. It doesn't harm her if she eats it, but if anyone else eats it, they will faint and fall into critical condition. She is 145cm tall. She closely resembles the "Reaper of Mercy," the very first Reaper who existed long ago. No one knows anything else about that figure. That Reaper was killed by the God of Destruction. There seems to be some connection between her and Flag-chan. However, no one knows this except for God (the Creator). Even Flag-chan herself is unaware.

Reaper No. 270. Flag-chan's junior Reaper. Strictly speaking, he is not a Reaper created by the Creator, but was sent from Hell as Fallen Angel No. 0 by the God of Destruction (the Creator's younger brother) to make the Angels and Reapers fall. His memories were erased before he was sent. Now, he works hard at collecting flags as a Reaper of the Celestial Realm. Among his fellow Angels and Reapers, he especially admires his benefactor, Flag-chan. He is shy, so he doesn't usually say it out loud, but he is grateful to her. A beautiful boy with ice-blue eyes and black hair. He has androgynous features and is sometimes mistaken for a girl. He insists, "Don't call me cute!" He is a handsome boy. His bangs are unevenly cut. His side-locks look like long hime-cut strands. The back is somewhere between a short cut and a bob. He wears oversized sleeves (moe-sode) and a black hoodie. He has something like a red leash hanging from his neck. He has gauze on his right cheek and bandages on his left thigh; when he falls from grace, his wounds are exposed. He calls Flag-chan "Senpai" (casual). He usually calls others "-san" or uses their name without honorifics. First person: I (soft/boyish). He loves games. He is 140cm tall and is self-conscious about being shorter than Flag-chan. He actually has a sweet tooth. He has a tsundere personality, so he sometimes says too much and gets into fights with Flag-chan, but they usually end up making up. He has a side like a pubescent boy. He often blushes when talking to Flag-chan. Could it be...?

Angel No. 51. The flags she collects are Romance Flags. She is a highly skilled Angel who makes love blossom, but she often prioritizes her own fun over flag collection. However, after meeting Flag-chan, a sense of "kindness" began to sprout in her. She cherishes Flag-chan. She calls Flag-chan "Shi-chan" and Ruin Flag "Ruin-kun." She is a beautiful girl with a pink skirt adorned with ribbons, a white blouse, a peach-colored bob cut, and red eyes. She wears a large ribbon on her head. First person: I (playful/boyish). She provides romantic support to try and hook up Ruin Flag and Flag-chan. She always carries Celestial items and is constantly plotting pranks. She has a surprisingly childish side. Usually, she is elusive and easygoing, but when she is serious, she is more earnest than anyone. She is 151cm tall. She pads her chest. No one knows what happens to those who find out.
