* CurbstompBattle: {{Deconstructed}}. Hina easily defeats her first opponents, knocking them out in a single blow. This is a problem for Valkyria since it is not good for gambling, which is their main source of revenue. [[spoiler: Nozomi even promises to give Yuzuha and additional million yen as a prize if she wins her match against Hina, specifically because she believes that Hina becoming uncontested this early will only hurt Valkyria in the long run.]]

* AmbiguouslyEvil: Chogen Takahashi was the leader of a cult that tried to coup the Japanese government. However, a former member of the cult claims that he only advocated for violent methods after adopting Hina and accuses her of changing him. The veracity of the testimony is debated InUniverse, so whether Chogen or Hina is the real responsible is unknown.

** Nozomi to [[Manga/KenganAshura Kazuo]]. She is a young woman who just lost her job while he is a middle-aged salaryman. Both of them serve as the main POV despite not being fighters, but Nozomi is experienced and could have gone to the public sphere if not for her CareerEndingInjury, while Kazuo gave up all hope of being a fighter long ago. Their relationship with the main fighter of their respective manga are also inverted: Kazuo often encourages Ohma when fighting and deeply respects him for his strength and [[{{Determinator}} refusal to ever give up]], while Nozomi is annoyed that Hina wins her fight too easily and is uneased by her strength and [[BloodKnight personality]].
** Hina to [[Manga/KenganAshura Ohma]]. Both them serve as the main fighter of their respective manga, but Hina is a outgoing and friendly girl while Ohma started as an asocial and rude man. Both are looking to fight strong opponents, but Ohma wants to both prove his strength and avenge his mentor Niko by defeating his killer, while Hina is looking for someone stronger than her. Ohma's first meeting with Kazuo ends with him asking Kazuo if he wants to fight and, when Kazuo refuses, he is disappointed but accepts it. Meanwhile, Hina's first meeting with Nozomi starts with them fighting and Hina wants Nozomi to fight her for real, despite the latter refusing.

* GrinOfRage: After being called slow by Hina, Toujou's face is deformed by a grin of pure anger.

* MusclesAreMeaningless: Hina only weights 50kg and is less muscular than her opponents. Despite this, she is strong enough to knock out experienced fighters with one blow. [[spoiler: [[SubvertedTrope Subverted]]/[[JustifiedTrope Justified]] in Chapters 9 and 15, where its shown that Hina is essentially in the same boat as [[Manga/KenganAshura Wakatsuki Takeshi]] in terms of possessing inhumanly strong muscle fibers that radically improves their [[LightningBruiser strength, speed, and durability]]. But unlike Takeshi, Hina has [[OneHeroHoldTheWeaksauce far greater control over her individual tendons]] as proven by her "[[SuperSpecialMove Rikudou Sunder Heaven]]", which is essentially the "Blast Core" technique but specialized to use only the muscles in ''just one arm.'']]

* FeudingFamilies: Chapter 18 puts the Jinguuji Family under Mitani Hana at odds with the Sanba Family under Inoue Sugaya. The Sanba have no respect for the Jinguuji due to the latter being one of the weakest Yakuza organizations in Japan's underworld, protected only by the fact that Hana's late father/predecessor had a close personal relationship with the boss of the dominant Niwa Clan, and sees their involvement in Valkyria's creation as a brazen attempt to intrude on the Slaughter Colosseum's business. After Yuzuha gets injured [[spoiler:losing her match against Hina]], Sugaya uses it as an excuse to try and poach Valkyria of their most promising fighters so they can finally crush the Jinguuji and absorb the rest of their assets in one fell swoop. [[spoiler:Thankfully, Sugaya's scheme completely falls apart when ''[[SpannerInTheWorks Hina]]'' decides to attend his meeting with Hana.]]

Nozomi gets the idea of creating a female only underground fighting organization to both get money and keeps the delinquents from fighting in the street, solving all of their issues with one stone. To help them attract strong fighters, they decide to recruit Hina Hongou, “the deadliest schoolgirl in Japan”, who was involved in a cult that tried to overthrow the Japanese government. But Hina might turns out to be too much for them to handle.
