History Manga / LifeWithAnOrdinaryGuyWhoReincarnatedIntoATotalFantasyKnockout

* {{Chuunibyou}}: Schwarz von Liechtenstein Lohen-Gramm, the hero that will save this world. The GratuitousGerman name that translates to something meaninglessly edgy, overly theatric mannerisms, wielding a self-proclaimed holy sword, and tendency to come up with elaborate scenarios on the fly such as when he assumes Tachibana has fallen in love with ParentalSubstitute Jinguuji, all paint him as a young man with a slim grasp on reality having a blast in a fantasy world. The Goddess of Night, the goddess that brought Schwarz to the other world, is even worse, to the point that Schwarz has to translate for her.

** They later meet another hero in the opposite situation, a high school girl who asked to become a young adult man. Unlike Tachibana, her transformation was entirely voluntary and was requested because her crush [[IncompatibleOrientation wasn't interested]] in a same-sex relationship.

* OreOnna: Tachibana still uses "ore" despite now being a woman since he still identifies as male, although he does switch to more feminine pronouns when intentionally putting up a girly front.

* SupernaturallyValidatedTransPerson: Chapters 103 and 104 reveal that [[spoiler:Lightning, hero for the Goddess of the Sun]] was a high school girl originally. Unlike Tachibana, however, this change to male was entirely his own choice after being informed of how summoned heroes get to pick their appearance.

* {{Bishonen}}: Jinguji is a very handsome-looking man who often sparkles whenever Tachibana stares at him.

* {{Expy}}: Schwarz shares [[LightNovel/SwordArtOnline Kirito's]] hairstyle and color as well as fashion sense, though he's pretty much the polar opposite in terms of character.

* SchizoTech: The world at large is a medieval fantasy setting, but the first dungeon the main characters come across is equipped with all sorts of out-of-place tech.

* AmbiguouslyBi: Basically the cornerstone of Jinguuji and Tachibana's relationship. They're clearly attracted to each other, but since Tachibana is in the body of a girl, defining their sexuality gets a bit hazier. Tachibana identifies as male and has always been interested in women, is in a woman's body and is falling for the male Jinguuji. Jinguuji shows no interest at all in any woman and actually much prefers the company of Tachibana, considering him his oasis, but only shows romantic attraction to him when Tachibana is in a woman's body--so maybe Jinguuji was always attracted to Tachibana and never realized. On the other hand, it's implied that Tachibana's charms works mostly on people who are already attracted to women. And there's the fact that it's possible both are simply under the effect of a curse. [[spoiler:A flashback suggests [[TheUnreveal but does not confirm]] Tachibana has been attracted to Jinguuji romantically since they were children, but his memories were [[FakeMemories altered]] right before he started to remember that.]]

* BlessedWithSuck: Played both ways. Tachibana's body change is shown to have its ups and downs. He's now in a much smaller body, so he isn't as strong as he used to be, and he also walks slower since his legs are smaller, however, he is also in a much younger body, which gives him less pains and gets rid of his shoulder aches as well as having more energy. Further, Tachibana's given skills such as Peerless Beauty, which requires a PerceptionFilter be used or he'll charm everyone around him, and Troublemaker, which makes Tachibana a WeirdnessMagnet.

** They later meet another hero in the opposite situation, a highschool girl who asked to become a young adult man. Unlike Tachibana, her transformation was entirely voluntary, and was requested because her crush [[IncompatibleOrientation wasn't interested]] in a same-sex relationship.

* GuileHero: Subverted. Tachibana is supposed to take this role, as his only skill is to charm others into doing things for him and his main stat as he levels up is luck. However, he tends to be too hot headed and impulsive to actually pull it off, and tends to use his CharmPerson ability as more of a blunt instrument.

** Tachibana is thirty-two years old, but his personality better fits the younger body he's transformed into. He rarely plans anything ahead, throws tantrums when he can't get his way, and is heavily reliant on Jinguuji to take care of everyday tasks.
** Although much higher-functioning, Jinguuji is NotSoAboveItAll, either. His social skills only hold so long as he believes others are treating him fairly, otherwise Jinguuji shows himself to be very short-tempered, selfish, and impatient.

* MoodWhiplash: After an adventure with another chosen hero, Tachibana and Jinguuji start walking towards the capital, the mood is peaceful, hopeful and friendly, but suddenly a carriage carrying a kidnapped Chieftess pass by them, and they decide to ignore.
* NeverTrustATitle: The English title indicates Tachibana "[[ReincarnateInAnotherWorld reincarnated]]" into his female form, which is debatable considering his body was physical transported to the fantasy world before being transformed (though the Goddess of Love does mention killing Tachibana before melting his body down to revive him).

* SchizoTech: The world at large is a medieval fantasy setting, but the first dungeon the main characters come across is equipped with all sorts of out of place tech.

* SignatureHeadgear: Early in the story, Jinguuji purchases a crown for Tachibana to wear that acts as a limiter on his powers, which seduce anyone who lays eyes on him. Without it, entering any populated area would cause every man nearby to fall over themselves to woo Tachibana. Prior to obtaining the crown, he caused an entire gang of bandits to turn on one another fighting over him. The crown causes Tachibana to go largely unnoticed, so his powers only activate when someone makes a point of looking at him. Naturally, Tachibana wears the crown almost always and, whenever it's lost or removed for some reason, chaos ensues.
* SoBeautifulItsACurse: Tachibana's female form is extremely beautiful and has passive skills that keep other people attracted to him. To some degree, Tachibana considers it CursedWithAwesome, lamenting his terrible fate while clearly enjoying every minute of all the attention he is receiving, but it does cause him genuine problems. Among the issues caused by being so beautiful is a band of thieves killing each other to be with her, and an elf chieftain fighting her and Jinguuji because she couldn't handle that there's a girl more beautiful than her. He is later selected as a sacrifice, since a Squid God wanted to eat the most beautiful girl his villagers could find.
* SummonEverymanHero: Each of the goddesses gets to choose one champion to defeat the demon king in return for a wish. They are ''supposed'' to summon people who are already dead, but Tachibana's goddess got lazy and decided to cheat. The hero that beats the demon king gets to make a second wish, which unlike the first wish can potentially include returning to life back home. As such, the less idealistic heroes have an incentive to kill off their competition.

* VagueAge: It's hard to be sure if Tachibana's new body is physically that of a teenager or a petite adult. The loose description it was based on includes being short and "young-''looking''", but also a "lolita". It's also an idealized body made by a literal god, so it could be [[TheAgeless completely ageless]]. Early on, Tachibana questions if Jinguuji and other men now attracted to him are all closeted pedophiles. Otherwise, even people unaware of Tachibana's origin mostly treat him as an adult, and don't question the idea of a romance with Jinguuji or other adults.

* SurprisinglyRealisticOutcome: The first time Schwartz uses his ridiculously powerful magic sword, his utter lack of experience with it causes massive property damage that he's promptly arrested for.

* BlindingBangs: When Tachibana was a guy, his hair constantly covered his eyes, and always had since he was a young boy.

* SoBeautifulItsACurse: Tachibana's female form is extremely beautiful and has passive skills that keep other people attracted to him. Among the issues caused by being so beautiful is a band of thieves killing each other to be with her, and an elf chieftain fighting her and Jinguuji because she couldn't handle that there's a girl more beautiful than her.

Tachibana identifies as male and has always been interested in women, is in a woman's body and is falling for the male Jinguuji. Jinguuji shows no interest at all in any woman and actually much prefers the company of Tachibana, considering him his oasis, but only shows romantic attraction to him when Tachibana is in a woman's body--so maybe Jinguuji was always attracted to Tachibana and never realized. On the other hand, it's implied that Tachinana's charms works mostly on people who are already attracted to women. And there's the fact that it's possible both are simply under the effect of a curse. [[spoiler:A flashback suggests [[TheUnreveal but does not confirm]] Tachibana has been attracted to Jinguuji romantically since they were children, but his memories were [[FakeMemories altered]] right before he started to remember that.]]

** They later meet another hero in the opposite situation, a middle school girl who asked to become a young adult man because her crush [[IncompatibleOrientation wasn't interested]] in a same-sex relationship.

* GenderBender: Shortly after being brought into the other world, the Goddess of Love melts Tachibana's body into goo, then reforms him as a female. Rather than having a female version of his original body, Tachibana's new form is based on his ideal of an attractive girl.

* TheChosenMany: There's twelve goddesses in the fantasy world and each one of them chose a Japanese as their hero to defeat the Demon King.
