YMMV: Shakugan no Shana

  • Base Breaker: Yuji Sakai after merging with the Snake of the Festival, and oooh boy is it almost as bad as Sasuke Uchiha. While he has clearly has well-intentioned goals, others consider him to be a borderline Sociopath who doesn't care about anything else outside of his goals.
  • Broken Base:
    • The third and final season has split the fandom between supporting Flame Hazes and Crimson Denizens — and in this case, Rooting for the Empire is quite understandable.
    • Geneon Dub VS Funimation Dub. That is all.
    • Yuji's Darker and Edgier Anti-Hero tendencies over the course of season 3 has left many fans grumbling about the drastic change in personality.
      • The problem stems a lot from the anime adaptation. Yuji expresses despair over the endless, ultimately nihilistic Flame Haze-Denizen struggle very early in the light novels, as well as a growing determination to do whatever it takes to end it. The Snake of the Festival, who shows up out of nowhere with no foreshadowing or buildup at the beginning of Shakugan no Shana Final, approaches Yuji from within the Midnight Lost Child and tempts him with promises of ending the eternal conflict. He also starts to exhibit a much more aggressive personality far sooner as well. For example, in the anime, when Wilhelmina attempts to kill him to prevent the Midnight Lost Child from falling into Bal Masqué's hands, Yuji does little to fight back. In the light novels, after Shana prevents Wilhelmina from harming him, Yuji takes the opportunity to try to kill Wilhelmina, and comes close to doing so. In short, Yuji's Face-Heel Turn, for a given value of heel, is not the abrupt switch the anime made it out to be, but a well-telegraphed and logical conclusion to his character growth.
  • Cargo Ship: Shana x Melon Bread has been shipped. Also, Shana has a What Is This Thing You Call Love? moment regarding melon bread and Yuji.
  • Die for Our Ship: Kazumi, especially after Pheles gave her a Treasure Tool which can summon Pheles, but would take Kazumi's life as a price.
  • Dude, Not Funny!: The ending of the Shakugan no Shana movie. Yuji, believing he's going to fade, finishes what he thinks is his "last speech" to Shana just as the Reiji Maigo replenishes him. Shana and Alastor double over laughing.
  • Evil Is Cool: Yuji as Snake of the Festival definitely fits the bill; his fans often nickname him as Darth Vader Yuji, or just Darth Yuji for short.
  • Evil Is Sexy: Yuji as Snake of the Festival has attracted a lot of fans over to his side because he took a massive level in Bishōnen. Honourable mention goes to Bel Peol, with her choice of clothing.
  • Fandom Berserk Button: It seems the correct form of Shana's catchphrase is "Urusai! Urusai! Urusai!!!"
  • Idiot Plot: Some feel this way about Season 3, in which the Denizens are simply trying to get out the Flame Hazes' hair and avoid having to Ret Gone any more humans. The only reason there is conflict is because the Flame Haze army doesn't trust them.
  • God-Mode Sue: Yuji after he ascended as Snake of the Festival; he basically and literally becomes God, and needless to say the strongest character in the series.
  • Memetic Mutation:
    • URUSAI! URUSAI! URUSAI!
      • URUCHAI! URUCHAI! URUCHAI!
    • OH GOD SHANA IS HOT
    • de arimasu~
  • Moral Event Horizon: To several people, Yuji driving Margery Daw towards the Despair Event Horizon, as well as the infamous scene between him and Shana during her captivity in the Palace of Stars.
  • Most Annoying Sound: Keisaku Sato's voice (his season 2-beyond voice actor to be exact; the season 1 voice actor was better-sounding for him)
  • Never Live It Down: Yuji is probably going to be forever remembered since season 3 as 'that would-be rapist world destroyer' no matter what positive qualities does he have.
  • Nightmare Fuel: Being devoured by a Crimson Denizen results in you being replaced by a Torch. Bad enough that your remaining life is spent as a sort of cosmic scab meant to insulate the universe from your disappearance. What makes this Nightmare Fuel is that when the Torch burns out, not only do you die, but no one will ever remember that you existed at all. There's an episode that chronicles Yuuji trying to save a Torch; watching her run down and burn out is equal parts Tear Jerker and this trope. If memory serves, the episode even ends with "What have we been doing all day?" when she does vanish. Brrrr.
  • Paranoia Fuel: At any time in the past, you may have been killed, eaten, and replaced with a copy without you even realizing it. And eventually, that copy can run out of power...
  • Rooting for the Empire: One interpretation is that the more Crimson Denizens (Guze no Tomogara) are in desperate need of resources and thus feeding on humans is sometimes the only option and some Flame Haze are overzealous. The former is backed up by the idea the Bal Masque was founded by a god, thus they essentially should have the same authority as Flame Haze (though they are not contracted with Crimson Lords). The latter is partially backed up by the fact that Margery Daw was originally shown as being somewhat of a Blood Knight and cared nothing but Revenge, thus indicating that there are more violent and less honorable Flame Hazes.
    • Rooting for the Empire became a more viable option in the later light novels (and the third season) when it is revealed Bal Masqué's plan, as well as their new leader Yuji's, is to create a utopia called Xanadu where Crimson Denizens will not need to devour humans to sustain their existence, and even coexist peacefully with them. And considering how the series ends...
  • The Scrappy: Kazumi Yoshida. Aside of the Die for Our Ship and Real Women Never Wear Dresses factors, there's the fact that people think she's shallow, boring, clichéd schoolgirl-in-love-for-a-classmate, steals too much screentime for her little romantic-anime antics, has a formidable amount of Common Mary Sue Traits and, for the final blow, her impact to the overall plot is almost null. A quick Google search turns up comments on her such as "The single greatest flaw with this series is that she isn't dead yet."
  • Squick: The Aizens, Tiriel and Sorath, make out with each other. In public. A lot.
  • They Wasted a Perfectly Good Plot: Yuji coming to terms with his upcoming Cessation of Existence with the knowledge that at least he won't be completely forgotten when he disappears could've made for an interesting story (even if the story had to go searching for a new male lead after that.) Instead, Yuji turned out to be a MacGuffin Guy that regularly restores his own Power of Existence.
  • Visual Effects of Awesome: One of J.C. Staff's best animated adaptations in recent years, and the third season simply escalate from there, culminating in the glorious Animation Bump that comes with the creation of Xanadu.
  • Wangst: Often resulting in combat. At times it seems like the series would be half as long if Shana and Kazumi wouldn't take so much time with their angsty internal monologues over Yuji, although Yuji himself is no stranger; he plays this trope at the end of the second season!
  • What The Hell Casting Agency: A lot of fans (especially those who were familiar with season 1's dub) didn't like Greg Ayres's performance as Keisaku Sato in Funimation's cast.
