Keyaru (ケヤル), also known as Keyaruga (ケヤルガ), is the main protagonist of Kaifuku Jutsushi no Yarinaoshi series. After years of torture at the hands of his own allies, he manages to break free and get the Philosopher's Stone. He then uses the item to go back four years time to exact revenge against the people who tortured him. __Apperance__ Keyaru is a young boy of medium height with brown hair and red eyes, initially he is dressed in simple clothes he used in the village, then after the start of his revenge he uses a set of armor he stole from the Captain of the Guards. When he uses his Heal skill, his eyes turn green. __Personality__ Pre-Betrayal: While little of who Keyaru was before the betrayal is shown, he used to be a kind and simple boy with dreams. After realizing that he was a hero he was excited to save the world, and although he was very different due to his class he was still happy and didn't realize Flare's true intentions for him until it was too late. Post-Betrayal: After being imprisoned, tortured, drugged and raped, his personality changes completely to that of a vindictive and sadistic individual. Because his naive personality allowed him to be taken advantage of, he changes to become a manipulative and cunning misanthrope full of hate towards those who abused him. Revenge is Keyaru's primary concern, although at least once he has mentioned the possibility of "living happily" once he has taken vengeance on his abusers. When asked why he seeks revenge, he says that the idea of people he hates being allowed to peacefully exist without consequences is disgusting to him. Contrarily to someone like Setsuna, he thoroughly takes pleasure upon taking vengeance, as seen by his happy laughter after having raped Flare and erasing her memories. The exception to this is the Knight Captain of Jhoiral's Guard, as even after the elaborate torture Keyaru devises for him, he shows absolutely no happiness nor satisfaction during it nor afterwards, presumably because the Knight Captain's actions resulted in the death of many of Keyaru's loved ones. One of Keyaru's redeeming factors is that he has no desire to harm those who have done him no harm, and in fact makes it a personal rule not to drag them into his revenge; this applies even to people who are otherwise cruel like Princess Norn (until he discovers that she had a hand in executing the captured members of his village). Keyaru also has some sympathy for people who strive for justified revenge the same way he does, and will do his best to help grant them their desire with the condition that they also help him with his. His relationship with the members of his party is hard to read. On the one hand, he commonly refers to them as his "toys" or "playthings" in his inner thoughts, implying that he has no real love for them and only sees them as tools. However, aside from some relatively very minor things (such as having Freia carry his luggage in revenge for formerly serving as the pack mule), he normally treats them only with kindness, completely at odds with his own treatment at the hands of Flare's party, and gets very agitated when one of them is harmed. Whether this means that he is more protective about them than one might think or simply possessive is unclear.
