YMMV / Saikyou Juzoku Tensei

• Angst? What Angst?: For a story that features a teen running away from his home and marriage, Abel's only missed his home and his sister for a few times. His parents (especially his mother) were barely featured worrying about him. Given what he encountered on his journey, it may have been for the best to not show them worrying.
• Audience-Alienating Premise: The Protagonist is reincarnated and born in a tribe of magic users who engage in Brother–Sister Incest marriages as the norm in their traditions, and he himself is a product of said marriages, and is promised in matrimony to his little sister! However, the trope is then subverted, as said tradition is only used as a motivation for his escape from the village to the outside world, to lessen the guilt from said escape, and the story instead cast his act of defiance of tradition in a good light, with him defying it in the ending.
• Base-Breaking Character:
  • Abel's reaction to his upcoming marriage to his sister can be... polarizing to some. Some claim his decision to escape the village was cowardly and irresponsible, even stating that he should've instead made his stance against the marriage pretty clear, adding the fact that he could've used his magic and control over the smoke-leaves production to strong-arm the whole village into letting him have his way. However, this goes against Abel's wish for a Slow Life Fantasy, let alone he's too much of a Nice Guy. His likability takes a dive after Volume 5 in the novel, where he ends up holding the Idiot Ball in order to show that he's Skilled, but Naive and can be tricked and put in danger along with Mea (after Volume 4 showed he's can be such a Crazy-Prepared and Properly Paranoid).. so he could make a comeback and beats the villains when they're close to winning against him. This pattern ends up getting repeated to make Abel less of an Invincible Hero, but ends up making him suffer from Forgot About His Powers and Aesop Amnesia. He also has a rather weird thought process regarding saving some really vile people who tried to earnestly kill him, almost looking like he's fishing for an excuse to save them.
  • Mea starts off as The Heart and the traveling companion for Abel, and helps fleshing him out as a friend and helps taking care of him, takes up archery (taught by Abel) to help him adventuring, and does have her moments to shine. But she's looked down upon because she often becomes the Designated Victim and the Damsel in Distress, when the villains have to force Abel into submission. Abel does acknowledge early that she's an open target, yet she insists on accompanying him. She's fully aware she's a Muggle Born of Mages and Can't Catch Up to threats to her and Abel, but her insistance on supporting him through thick and thin is both detrimental and redeeming to her quality.
• Creator's Pet: According to Word of God, Gaston is this.
• Ensemble Dark Horse: Out of all the characters who stayed in for awhile and dropped off never to be seen again, Maizen earned the manga (and the novel) readers' love because of his endearing personality and genuine kindness. There also his tendency to run from danger to protect others from it making him the target of a few memes!!
• Epileptic Trees: A line in Chapter 48, uttered by Mea when Abel suggests throwing away his bag of dried-up Greater Bear Meat, has her using the word "protein". The story established fairly early that Abel's current life is in a medieval-like time mixed with swords and sorcery, where terms like this may not been invented yet. This led many of the webnovel readers on the original website to suspect Mea of being a reincarnated person herself (even believed to be Abel's previous life female underclassmen I-chan). The author seems to have caught on, and nothing like that ever happened again.
• Just Here for Godzilla: Admit it. Many, if not all, were drawn to the novel just from the idea of a tribe that treats Brother–Sister Incest marriages as the definitive norm for an in-universe reason, and the protagonist's sister becoming a yandere and chasing after him when he escapes their Arranged Marriage.
• MST3K Mantra: Any discussion about how the Marren tribe haven't perished yet to genetic disorders from their incest marriages can end with this answer.
• Portmanteau Couple Name: Put the first Katakana letter in Melzef (メレゼフ) and the last letter in Nelea (ネレア) together and you get... Mea (メア).
• Squick: The reveal of the Marren clan's marriage customs.
• They Wasted a Perfectly Good Character:
  • Filo. She's introduced as a safe Love Interest for Abel in the Marren tribe, if a little tsundere and Cannot Spit It Out in their interactions, is shown distraught over the news of his incoming marriage and greatly misses him after he left... Only to be Demoted to Extra, put through the wringer from the journey to bring Abel back, finally meet him, scold him and confesses that she could've helped him in the village had he asked... then Abel kindly rejects her in favor of Mea, and is left out of the plot, getting a small mention in the epilogue for helping Abel get accepted in the village again.
  • Filo's pet Loops deserves a mention. A close companion to Filo and is shown (in the manga at least) as friendly and accepting of Abel approaching it's master. Yet it's never mentioned again in the novel after Abel leaves the village, missing a good opportunity to include a dog to the Abel Search Party to help tracking him, or at least protect Filo.
  • Mea's big brother Darrel. He's solely mentioned in Mea's Origins Episode, and was stated to have grown from a Big Brother Bully to a Cool Big Bro for his sister, but was never mentioned again before and after Mea leaves the settlement. He should at least have something to say or do.. about his mother getting Taken for Granite and his father going on mission to kill his sister.
  • Zolomonia might as well be the biggest offender in the novel. After forming a contract with Abel and helping him with her powers fight off Kudor by the skin of their teeth. Instead of becoming a valuable ally for Abel .. she's sealed in a storehouse to spend her time deciphering magicbooks and texts. Abel's justifications for that is, since she's such a Wild Card, leaving her free is a risk he's not going to take.
• Unintentionally Unsympathetic:
  • Abel's reaction to his incoming marriage to his sister can be... polarizing. On one hand, he knows from his previous life of the potential risks like birth-defects (which he did try talking his father out of it, but he didn't understand), along with making Giselle grow attached and dependent on him, fearing that his village will strong-arm him into marrying her (which is proven correct, when his father arranged for the wedding to be after three days), and wanting to be free and out of the village. On the other hand, Abel left an abrupt letter explaining how he'd only see his sister as a... sister and he's sorry about that, and that he'll return after he's gotten married, or Giselle gotten married instead. This could be interpreted the wrong way (and it's implied Giselle crumbled the letter and ignored its content), leading to his sister turning Yandere and manipulating the village into forming a search party.
  • The issue with the letter was downplayed in the Light Novel's extra chapter “Giselle's Struggle”. Where it was shown that indeed, Giselle did read the letter!
  • Peter, despite becoming a Reasonable Authority Figure to Abel, his greatest asset, friend and who also saved Abel from a sticky situation and had reasons to becoming a Well-Intentioned Extremist... still comes off as an Easily Forgiven monster who took two teenagers captives and tried to have them killed because They Knew Too Much, and came very close to killing Abel through an underhanded method. Abel even rescues him from a Laser-Guided Karma on the flimsy excuse that he would've spared Mea after killing him, disregarding the fact that Peter would've still murdered him, left his companion to mourn him (unless she's killed as well), and would've been killed by Kudor without Abel to save him!! Any reason to wonder why there is catharsis felt when Peter realizes that this past incident maybe made it hard for Abel to trust him with his and Mea's life??
  • The Riveras Kingdom, Levi Church and Sateria were supposed to be viewed as victims of their Evil God Levi manipulations, after he's revealed to be the False God Med. However, that happens after they've committed several acts of terrorism and hostility, that claimed several lives (see: Nalgarn). Driving nearby villages to decline with sabotage, monster attacks and diseases, to attempts at abduction and assassination. Most of the perpetrators were portrayed as Sinister Ministers who fully embrace their role in their war against the "infidels". Yet the kingdom ends up getting a happy ending handed to them by placing a fake deity (based on Abel) to end their civil-religious wars.
  • Giselle can be seen as a victim of the circumstances and her tribe's traditions, with the way her brother ran away from the Arranged Marriage she was promised of ever since she was a child by her parents. However, it's shown that she willing to trap her brother against his wishes in said marriage, becomes unhinged day after day from the anxiety, drags her companions in the Abel search party on tiring journey, is willing to attack and inflict near-lethal body harm to her brother's female companion, in addition of being Not Brainwashed! Giselle's actions wouldn't have an ounce of charm if the genders were reversed (A brother forcing himself on his sister, anyone?)
