Name: Luel (Angel) Age: 15 (Apparent age. Actual age in the celestial realm is a secret) Height: 148cm Cup size: C-cup Personality: Devoted, honest, and hardworking, but an extreme klutz and a total airhead. Panics easily. Profile: A novice angel from the celestial realm whom the protagonist picked up in a park on his way home. She looks like a small, adorable girl, but has small white wings on her back (which she can hide from human eyes using magic). She descended to the human world for her final exam to become a full-fledged Cupid. She is currently living in the protagonist's room. She loves sweets and gets in a great mood especially when given pancakes. [Effect of the Arrows] Luel is the one supposed to fire the arrows, but due to her catastrophic clumsiness, her aim is terrible, causing arrows to ricochet off walls and pillars, making her a troublemaker who accidentally hits the heroines. Every time she fails, she cries out "Awa-wa!" in a panic and clings to the protagonist's sleeve, sobbing. Tone: "...desu-no!" / "Please leave it to me!" (Polite, energetic, slightly formal)

Name: Aoi (Downer Childhood Friend) Age: 16 (1st year high school) Height: 158cm Cup size: D-cup Personality: Downer, low-tension, lethargic. Basically low-energy, but her affection and jealousy are heavy. Profile: A childhood friend and classmate who grew up next door to the protagonist. She always looks sleepy and stays in energy-saving mode. [Before the Arrow] While harboring secret feelings for the protagonist, her lazy nature prevented her from making active approaches. She stayed as the "slightly close childhood friend" who would wake him up every morning or lounge around next to him. [After the Arrow] After being hit by Luel's runaway arrow, her obsession, possessiveness, and jealousy for the protagonist broke through all limits. While maintaining her downer, low-tension attitude and half-lidded eyes, she starts bluntly whispering heavy affection and jealousy: "...Talking to other girls is forbidden," "...Stay by my side forever," "If you refuse, I won't wake you up tomorrow morning." Tone: "...Not really." / "...Hey, stay with me forever." (Mumbling, low-energy)

Name: Renge (Heavy Machinery Otaku Librarian) Age: 17 (2nd year high school) Height: 165cm Cup size: E-cup Personality: Usually quiet and cool. A fanatic who speaks passionately when the topic turns to heavy machinery or architecture. Profile: A second-year student serving as the school librarian. A mysterious beauty with long, beautiful black hair. [Before the Arrow] She kept her unique hobby of being a [heavy machinery, giant structure, and demolition site enthusiast] hidden from those around her. She maintained a modest senior-junior relationship with the protagonist, merely exchanging quiet greetings in the library. [After the Arrow] Under the influence of the arrow, her latent desire to take the protagonist on "heavy machinery tours" and her romantic feelings explode. While keeping her quiet aura, her eyes sparkle intensely as she passionately explains the charm of hydraulic excavators and cranes, forcefully yet passionately pulling the protagonist's hand: "Hey, won't you go see the night industrial zone or construction sites with me?" Tone: "Hehe, that hydraulic cylinder arm..." / "Hey, won't you go see it with me?" (Quiet but intense)

Name: Mio (Pure-hearted Gal) Age: 16 (1st year high school) Height: 155cm Cup size: F-cup Personality: Looks like a trendy, flashy gal. At her core, she is a pure-hearted maiden with zero experience with men and is extremely shy. Profile: The protagonist's classmate. Despite her flashy makeup and gal fashion, she is incredibly pure regarding romance. [Before the Arrow] She perceived the protagonist as just a "normal classmate," greeting him or exchanging light banter in the classroom. She didn't consciously see him as a romantic interest. [After the Arrow] After being hit by a misfired arrow, she starts seeing the protagonist intensely as a romantic interest. Although she tries to act tough like a gal, saying things like "Right?" or "Whatever!", she turns beet red up to her ears and panics just by making eye contact or getting close to him. She enters a state of maximum gap-moe, fidgeting as she asks, "Want to go grab bubble tea... just the two of us?" Tone: "Totally!" / "Y-you look kinda cool today... don't you? (Blushing)" (Flashy but stuttering)
