In the main story
- In the one of the earlier chapters, an indestructible being that can absorb any form of attack thrown at it, soon acquiring the abilities of another being that kills most things just by being near them and whose touch is potentially deadly to absolutely anyone, is loose in Gensoukyou. It swiftly dispatches its millenia-old creator, a Reality Warper, two stupidly powerful magicians and a bearer of impervious Plot Armor, leaving only Suika to fight it. After her treasured gourd is crushed in the battle, Suika acts exactly like Suika, proceeding to pound the ever-loving crap out of the life-ending monstrosity, leaving it (temporarily) broken and unconscious in a crater. Moral of the story: never force an oni to be sober.
- The Storm: Being a massive throwdown between everyone Yukari can shanghai into assisting and Yuuka Kazami, much awesomeness (mixed in with terrible situations and the occasional Tear Jerker) ensues. Highlights would need to include Yukari summoning and detonating an oil tanker in Yuuka's face.
- Notable as well is Marisa's usage of "And The Sun Rises Red". And Marisa's trick with the manually detonated spell cards. And that one time with the missile- aww screw it, just everything that Marisa does in that fight.
- Finally, the very fact that Yukari managed to essentially Mind Rape an Old God.
- How about the fact that Yuuka Kazami manages to, in what was supposed to be a one-on-one duel until Yukari cheated, laughingly curbstomp Remilia, Flandre, Sakuya, Orin, Satori and Utsuho using only a fraction of her power. She then goes on to bring three quaters of her power to bear against Physical God Yukari and manages to put her out of comission so badly that she's been unable to take any real action for seven chapters. The only fight she lost was against Mima, Marisa, Yuyuko and Youmu, and she had them on the ropes at the end of the fight, with Marisa having to use multiple Dangerous Forbidden Techniques that almost burn her out. Say what you want about her character, but damn if Yuuka isn't awe-inspiringly powerful. Awesome doesn't have to be good, after all.
- The Strutter vs The Hisoutensoku.
- In the 41st chapter, Kanako Yasaka successfully fends off Eldritch Horror Yuuka Kazami by essentially guilt tripping her.
- Rin Satsuki gets a moment of her own a bit earlier. She manages to annihilate said Eldritch Horror's anti-magic field and give her an Oh, Crap! moment in one go.
- Roughly every Pre-Asskicking One-Liner in the series, as well as several smartass retorts by the characters in everyday conversation.
- Chapter 21, when Byakuren gives Kanako a very much needed What the Hell, Hero? for causing the events of Subterranean Animism. Doubles, after, as a Heartwarming Moment when Kanako talks with Sanae, since it shows that while Kanako is jaded, rash and selfish, she has a heart, and she's capable of doing good.
- Chapter 42, Reimu argues with Yukari over Rin Satsuki, and convinces her to give Rin a chance.
- Chapter 57, my goodness. Yuuka challenges Marisa to a duel over Marisa managing to escape unscathed in The Storm chapters. Marisa forces Yuuka to break promises and break the rules she herself agreed to. And still wins. Except, Marisa decides that killing Yuuka would damage her soul, and lets her go. This doesn't work out for the best.
- Chapter 66, After being smacked around by Yuuka the entire fight thus far and unable to do anything but run, Rin turns the tables in a truly epic fashion after absorbing Flandre (at her request). This gives her such an immense boost in power that Yuuka goes from effortlessly blocking Rin's attacks with one hand to lying in the rubble of a wall with a shattered arm and wondering what just happened.
- Chapter 67, Rin makes very good use of Flandre's Taboo: Four of a Kind, laying a magical and physical beatdown on Yuuka that leaves the latter spitting up blood.
- How do you deal with a fragment of an Outer God that has just abandoned it's human form and become a formless mass of darkness? If you're Rin, incinerate it with phoenix fire.
- How does Yuuka counter Rin's clones? Make some of her own.
- Rin survives being impaled by Gungnir and dismembered by said divine spear, getting back in the fight shortly afterwards. This freaks Yuuka out so much that she loses control over her stolen weapons.
- Chapter 68, Rin reenacts a game of whack-a-mole with Yuuka as the hammer. Doubles as a CMOF
- Adding on to Rin's already ridiculous list of survival feats: she gets stabbed by the mordite knife that Marisa used against Yuuka and manages to not only survive, but recover and resume fighting immediately afterwards. Something that Yuuka herself, a fragment of an outer god, very explicitly could not have done. Even Shinki is stated to need a couple weeks to recover after a similar wound and is unable to even move after the injury.
- Yuuka takes advantage of the pain the knife causes and invades Rin and Flandre's minds, trying to break them with their worst fears, only to spill the beans about Marisa's death and piss off Flandre enough that she breaks the illusions, grows to giant size, and together with Rin throws Yuuka right out of their head. Made better by Yuuka perceiving it as them throwing her out of the spotlight and shattering her delusions of main-characterhood. This was also where the above example comes from: despite having been stabbed with the knife immediately before the attempted mindrape, there's no damage after Rin and Flandre kick Yuuka out.
- And finally, Rin crushes Yuuka's Eye, reducing her body to dust. Though Yuuka survives this, she's left with two fragments of her remaining, each only a sixteenth of her power, both reduced to emaciated husks, and both the prisoner of someone who they looked down on (Yukari and Mima). To top it all off, she can still hear the readers laughing at her defeat and is so broken that she can only laugh with them. Rin doesn't just beat Yuuka, she utterly destroys her.
- On a side note: Utsuho not only stays in the mansion during all of this to try and find Satori, but manages to do so despite the fact that the building is full of Yuuka's plants, all of which try to kill her, and how Rin and Yuuka are throwing down in the same building.
In Rhapsody of Subconscious Desire
- The friggin' Zerg make a cameo appearance. It's every bit as awesome as it sounds.
- Kaguya's (imaginary) second trial in the Lunar court. The way she utterly demolishes her arrogant and homophobic father is a absolutely spectacular.
- Also, a few chapters later, Kerrigan herself appears for a scene, as the embodiment of Kaguya's subconscious. Oh, Kaguya. Never change.
- Mokou sticking it to the avatar of the Angel of Death herself, telling her that she can't die, and her puny angel of death powers don't change that. Yagami's reaction is a complete Freak Out, and the first time in the story when we see her genuinely shocked and afraid.
