* InnocentCohabitation: Despite the fact that Satis and Sato are very, very much into each other, sleep in the same bed, share a bath, etc., they keep things innocent while living under one roof because being hunted by both the Demon King's army and the human army as "deserters" when they were in fact expelled from their respective forces keeps them from giving in to their desires, for fear of their lives.

* DwindlingParty: The moment Reid expelled Sato from his party, their numbers began dropping like flies until only Reid is left with [=McLean=] dying from overexertion, Hydra being sent off on an ImpossibleTask due to merely suggesting Reid is wrong and Angelica dying in a struggle when she tried to kill Reid after convincing him to steal from merchants.

* MagicKnight: In the setting, there are few swordsmen capable of wielding magic swords, which makes them all very powerful warriors in their own right.

* MagicKnight: In the setting, there are few magic swordsmen, but they are all very powerful warriors in their own rights with them being highly valued as part of their respective armies.

* OutcastRefuge: Benjamin Village's population is lost souls or "eccentrics" as they call themselves, who came to the village after losing their purposes and are in need of some kind of company.

* TheCallKnowsWhereYouLive: The reason Sato and Satis keep getting dragged into conflict. It doesn't matter where they try to put down roots, the human/demon war keeps finding them. Eventually, they managed to get on the good side of a human noble who is a talented soldier and general in his own right and even then, one of the Demon King's armies comes for them and Sato finds himself locked in battle with Sabo, a maniacal AffablyEvil BloodKnight that just wants to fight him to the death purely for the thrill of it.

** The "Hero" party expelled Sato because the self-proclaimed hero just unilaterally decided that Sato's brutal and efficient fighting style lacked "justice" and was disgusted. Since Sato was the only member of the party with essential ''survival'' skills, like cooking, being the look-out, standing watch at night, etc. The party quickly fell apart and the "hero" was called to task, and the Martial Artist was sent to look for Sato, but by then, things had already passed the point of no return and party members began to drop like flies, SlowlySlippingIntoEvil, or both, while still trying to tell themselves that they're working for the "greater good."

* SlowlySlippingIntoEvil: After expelling Sato from the party, the "Heroes" start making compromises with their own moral standards. By the end of it, the party has turned to banditry, and the "Justice loving" hero himself has straight up killed one of his party members with his own two hands and can only cup his head, going into a complete and total nervous breakdown, still trying to convince himself he's the good guy.

[[caption-width-right:350:Behold the couple composed of former enemies.]] Sato was a ChildSoldier and unwilling gladiator conscripted to aid the Hero party in their quest against the Demon King, until the so-called "hero" unilaterally went full-tilt HolierThanThou and threw him out of the party, (at least in the manga) without consulting the rest, leaving him to his own devices. Satis was the leader of the Demon King's armies and his top strategist, until she experienced one too many defeats at the hands of the same "Hero" party and was not only summarily dismissed from her post, but slated for ''execution'' to MakeAnExampleOfThem. In both cases, things quickly fall apart because they both were the backbone of their respective armed forces. Through an unlikely string of coincidences, Sato and Satis meet and bond over their eerily similar circumstances. All they want is to be left alone and live in peace, but neither side will let them.

* ChildSoldier: Sato was conscripted into the army before he was 10 years old. Before that, he was a gladiatorial slave, hence his ruthless and highly efficient fighting style.

** Satis was the leader of the Demon King's armies and his top strategist. The Demon King just decided one day that Satis needed to go because she lost at the hands of the "Hero" party too many times, not only removing her from her post, but sentencing her to ''execution'' to make an example of her. The demon armies, now without an overall commander, and not wanting to risk execution themselves for failure, quickly become disorganized mobs and retreat from winnable fights, scatter like the wind, or just try to follow their standing orders without a strategy of any kind and dash themselves against heavily defended human outposts to the last man.
