Needs More Love and Wiki Magic

• Ambiguous Innocence: Nagihara Sora. Her innocent nature is most obvious in Chapter 8 when she has a strongly Luminescent Blush when she is asked to cook food for her master. Other times though ...
• Applied Phlebotinum: All of Sora's martial arts techniques seem to come out of nowhere
• Anatomically-Impossible Sex: An in-universe example in that until chapter six, Sora thought that girls got pregnant when one ejaculated on their face.
• Breast Expansion: Tenka the flat-chested girl got some "improvements" from Sora in chapter 3, almost Gag Boobs, and yes she keeps them.
• Buxom Is Better: Sora tells Tenka, "Boys like big boobs." Also, as she's supposedly seeking out people to bear Shouta's children, she seeks out those with more 'motherly' figures.
• Catgirl: Sort of. Sora actually is based on a terminally-ill manga character who wears fake cat ears, so that when she gets reborn, it might be as a cat. She's certainly invoking this trope, though.
• Childhood Friend Romance: Ryoko Kaburagi certainly seems to be a contender for the harem.
• Completely Missing the Point: Sora and especially Tenka's mother fall victim into this trope very often.
• Cute Bruiser: Nagihara Sora. 2D Art of Death, indeed.
• Does This Remind You of Anything?: Invoked intentionally by Sora. She... tends to do this...
  • Such as when she makes Shouta spill ramen on Ryoko. She follows it up with "You ejaculated on her face!"
• Ecchi: And occasionally pushing the envelope...
• Harem Seeker: Nagihara Sora
• Magical Girlfriend: An Affectionate Parody of the genre.
• Mood Whiplash: It is a manga by Minazuki Suu after all.
• Oblivious to Love: Yamakawa Shouta
• Refuge in Audacity: For a while, no one was willing to translate this manga.
• Take Over the World: Sora's plan for Shouta. He wants no part of it.
• The So-Called Coward: Yamakawa Shouta especially whenever a Drama Bomb drops.
• Tsundere: Ryoko Kaburagi
• Wham! Episode: Suprisingly.
  • Chapter 7: The Real (Or is it?) Nagihara Sora appears from the doujin.
  • Chapter 8: The other Sora is an extreme Bitch in Sheep's Clothing.
