YMMV / My Instant Death Ability is So Overpowered...

• Base-Breaking Character: Viewers either like Yogiri, or they don't. Many accept him as the logical extreme of his Overpowered Protagonist archetype and like how alien that makes him come off as, even before he's revealed to be the incarnation of an unkillable Eldritch god, but others believe that those same traits make him tedious to watch.
• Complete Monster:
  • Volume 5: Raiza is obsessed with finding a Worthy Opponent to give him a good fight, and to this end built a city to draw in challengers in the hope of eventually getting the fight he wanted. Raiza forces the martial artists of his city to fight in combat to produce an opponent. Unable to find a worthy foe, Raiza began attacking villages, killing people and raping women, hoping that people would train all their lives to become strong enough to challenge him. Raiza has produced children from the rapes he has committed over the years and sent them in their adult lives to also Rape, Pillage, and Burn villages in his name.
  • Volumes 10 & 11: Ultimate Extermination God (UEG) was the top goddess, and the ruler of the multiverse. At some point in time, UEG became obsessed with death and destruction and developed a bloodlust for it. A nigh-omnipotent Psychopathic Womanchild of a goddess, UEG became drunk with power and began erasing worlds one at a time. Eventually, two gods were sent to stop her; unable to best her in power, they used a special technique to seal UEG within another universe. After UEG is released, her goal is to erase all the other gods in existence. Though she could destroy the entire multiverse and space-time along with all the other gods in an instant, UEG chooses to slowly go around wiping out life slowly, due to her sadism. UEG goes around destroying cities and erasing people from existence, while looking for other gods to erase.
• Crosses the Line Twice: Sion. A beautiful, happy-go-lucky, sweet, and sunny Genki Girl Nice Girl Girl Next Door who is also a ruthless believer of Might Makes Right and instead of being a facade, her cheerful and sweet demeanor is genuinely hers, along having the mindset of a videogame in every decision she made ends up making a lot of viewers/readers like her. The manga and anime adaptation makes her appearance and personality even more visible helps with the regards.
• Fridge Brilliance: Having Femme Fatales to spy on Yogiri makes sense due to the latter having a positive relationship with one woman in particular, Asaka. Also, it's no coincidence that each girl has at least one trait of Asaka.
  • Ryouko is a dark-haired woman like Asaka.
  • Carol is cheerful and friendly towards Yogiri because Asaka has been a kind caretaker to him.
  • Ayaka has a near similar name to Asaka.
• Heartwarming Moments: Any of the flashbacks with child Yogiri and Asaka are full of these, despite also being the most horror-themed parts of the series.
• Fridge Horror: Yoichi being slowly left to die in a floating castle because Sion can't go back to him. The light novel at least had Sion, before going back to Yogiri and pleading to spare Yoichi, put Yoichi to deep sleep to ease the discomfort of losing the body parts, making it a magically induced Dying Dream because Sion can't manage to wake him up.
• Love to Hate:
  • A lot of the viewers/readers took a liking on Sion, because despite her obvious villainy in action, her cheerful, carefree, sunny, and sweet demeanor without any apparent facade or stereotypical smug / cackling villainy is endearing. The manga and anime adaptation made her appearance and personality more pronounced, along with her voice actress also helps.
  • The same goes to Vahanato, adding her extremely attractive look on display and her villainy is even less shown.
• Moral Event Horizon: Sion telling the Sage candidates to kill each other until there is one left is what makes her crossing the line from Comedic Sociopathy into genuine villainy. The light novel even had Yoichi, her assistant and implied lover, said that it's a waste, given that when they was a candidate, there's never a Battle Royale style confrontation.
• So Bad, It's Good: Due to the Deconstructor Fleet approach to the Isekai Cliché Storm while still maintaining some of the cliches with unpredictable randomness of various trope implementations (such as Anachronism Stew and Reset Button) as the series goes on, many view the series as this.
• Tearjerker: Sage Sion's gradual loss of bodily functions thanks to Yogiri, and later, her completely innocent assistant and implied lover Yoichi as well. Sure, she's probably deserved it, but that's too much for the two. The eye-catch in particular hits really hard. Luckily, despite post-Reset Button, their disabled body remains disabled, they have gotten over it and could live their daily lives unimpeded by using magic to support them.
• They Wasted a Perfectly Good Character: Done to the point of parody, where uniquely-designed characters are dying left and right despite their extent of bad things is just that they're opposed to Yogiri and while some of them do have their villainous moments, some others had their villainous act mostly informed and there's those that haven't done a lot of things to be qualified as villainous, let alone a Jerkass.
• They Wasted a Perfectly Good Plot: The another world setting being a Fantasy Kitchen Sink with fantasy, magic, and technological elements in one world along with an abundance of otherworldly invaders, demon lords, Humanoid Abomination, and Eldritch Abomination in the world can be more interesting and still breaks common cliches even without somebody with an instant death ability as the protagonist going around.
