Blade

Blade (ブレイド Bureido) Is the main male protagonist of the manga Eiyū Kyōshitsu and a student at Rosewood Academy where he met Arnest Flaming.

Appearance
Blade is an average sized teenager with a slim figure. His most prominent feature would be his hair, which is black on the left half and white on the other giving him a unique look. Though originally it wasn't multi-colored, this change happened after Blade lost his powers.

Blade's torso has several scars on it. It's also said that his lower body also has many injuries and scars, most likely from past battles.

He's usually seen wearing the school's uniform which consists of a white school shirt with a black leather coat covering the shoulders and a burgundy casual tie, black leather trousers and black leather boots. He also carries a sword around his back.

Personality
Blade is an easy going, carefree individual who uses simple language to deliver his meanings, However, he possesses a mysterious character as he refuses to reveal intimate information about himself, usually ever so nonchalantly evading questions relating to him or changing the subject, something that annoys Arnest very much.

Blade's goal is to make one hundred friends during his time at Rosewood Academy and he has made six friends so far, Arnest being one of them, despite the latter denying it. He also gets extremely irritated by the King's constant accusations of him having "a thing" for Arnest.

However, when the times call for it, he can become very serious and quite reliable in combat as seen when he encountered the demons, completely unfazed and composed.

History
Sometime in the past, Blade lost his powers and his hair altered colors. He met King sometime before joining the academy and seems to be very familiar with the later.

Transfer Student arc
Arriving at Rosewood Academy, Blade raises his fists to the air and yells loudly "I'm a commoner" outside the school building, announcing his arrival.

Struggling with her own issues, Arnest was in the ladies' restroom washing her face when her sword's demon, Asmodeus approached her only to be rejected easily. As she walks out of the restroom, she is greeted by Blade's face yelling "I'm Blade", startling her at first but was quickly disregarded while Blade continued to repeat his phrase. Annoyed by his actions, Arnest decides to punch Blade but he easily evades it much to her shock. He continues to make a few moves around himself when they were interrupted by the King who explains to Arnest about Blade and asks her to take care of him during his time at the school, despite her protest.

Blade offers a handshake that was turned down by Arnest who scolded him for his misjudged behavior, telling him that he isn't the right material for the academy and accusing him of being goal-less. Blade replies that his goal was to make lots of friends, a hundred of them.

Blade's actions begin to infuriate Arnest more and more by the second when she notices him sleeping in class. He was then approached by Leonard who introduced himself and Blade tells that he's number six, explaining that Leonard is his sixth friend since arriving to the academy, the others being Claire, Jessica, Kraid, Kassim and Arnest who gives them a deadly glare and says that their training class is next, conspiring to reveal Blade's "true colors" believing he's a faker. She stops the class and asks Blade to take the field where she challenges him to cut a magical armor made of Mithril and Obsidian alloy which is two to three times tougher than normal iron armors. If he doesn't pass her test he will have to leave the school immediately. Blade calmly accepts the challenge as Arnest throws him a sword.

He says that he isn't very good at measuring his own power before swinging his sword forward, creating a single slash that easily destroyed the magical armor, the earth and the academy's magical barrier. Looking with disbelief, Aenest, enraged as ever, goes back to her dorm and takes a shower to calm herself down, thinking back to what happened that day when Blade suddenly popped at her window. Quickly covering herself up, she takes her sword and attempts to hit him only to fail with Blade grabbing the sword with his bare hands. Blade mentions that her sword is cursed, saying that he could recognize a cursed item just by looking at it since he's seen many similar to it in the past. Arnest denies that fact and threatens him out when Asmodeus manifested himself before her, saying that this kid is interesting but dangerous and they must slay him. Arnest rejects the sword's will saying that she won't allow it to have its way.

Asmodeus Arc
The following day, Blade is seeb in front of the academy, correcting a student's swordplay which Arnest takes as flirting. While Arnest was at her table in the school cafeteria, Blade places a dozen of plates on the table and takes a seat much to Arnest's confusion. She comments sarcastically that he's really enjoying his school life then tells him that the other students do not sit with her. However, Blade was not paying attention, inviting Claire and Jessica to sit with them who walk past him in fear of Arnest. Blade questions with a sympathetic face if Arnest is being bullied which the latter quickly denies. Arnest tells him that he's talking to her awfully casually after what he did, exclaiming that he peeped on her in the bath, dragging all the students' attention to them as Arnest calms down. Blade eating his food hears Arnest admitting that he is stronger than her and apologizes for suspecting him before. Blade asks if she really did that which she confirms. Joyfully, he tells her to not worry about it since it is something he completely forgot about, it meant that he didn't really care. That, and the fact that they're friends now which shocks Arnest, he tells her that if they weren't friends they wouldn't be sitting and eating together. Arnest leaves the table and Blade shouts that if she doesn't want the rest of her food he will eat it, deducing that she doesn't and prepares to eat however, Arnest stops his hand and says that she changed her mind. Blade watches as Arnest leaves the cafeteria.

Following those events, The King prepared a tournament for all the students to compete against each other. Blade protests and complains about it but was disregarded, cursing the old man who tells the students that the winner of this tournament gets to fight "the hero". A flustered Arnest then tells Blade to do his best as will she which Blade agrees to. Blade is next seen defeating Leonard in a single punch, apologizing to the latter who says that for a person who defeated everyone in a single punch, he really has no sense of remorse. Leonard then tells Blade that his next match is bound to be a tough one since he will have to fight the winner between Sophitia and Arnest, giving the upper hand to Arnest because of her cursed sword. After defeating Sophitia, Arnest prepares to fight Blade who tells her that she might want to forfeit since she is heavily fatigued while he's still in top shape, Arnest refuses and while she speaks, she is consumed by Asmodeus amidst Blade's awe.

Later that day and after waking up in the academy's clinic, Arnest finds Blade being hit on by The Doctor. Blade ignorantly welcomes her and tells her that she passed out and asks her what happened back then however, Arnest punches the boy. Blade follows Arnest outside the clinic, telling her that she should rest more. Arnest asks if she said anything while she was unconscious which Blade responds to that she didn't say much however, she was a little tough to carry, explaining further that it was because she wouldn't let go of the sword that she was tough to carry. Blade asks why there was a haze coming out of the sword and its relation to her passing out. He tells her that the sword is affecting her and that she should tell him about it but Arnest refuses, asking him to not tell anyone about what happened however, Blade was not satisfied with that answer.

Blade notices King behind the corner who've been eavesdropping on their conversation. The King then accuses Blade of being rejected by Arnest which Blade denies, attacking the King afterwards and strangling him. King questions if that's the type of girl "Blade-chan" goes for. Blade asks if he knows anything about Arnest which King (much to his fancy) teases the boy more about. King then says that he isn't willing to give away information about his students so easily, giving Blade the key to the Royal Library of Banned Literature, saying that he will find everything he needs to know there. Blade goes to the library which is located under the Royal Palace, encountering the Library Guards who say that they won't let him pass and calls him "Hero Blade". Blade, showing his immense speed, travels around the guards and says that he's "former Hero Blade", cursing the King for fooling him.

After defeating the Library Guards, Blade finds a table with a computer installed on it, looking up information he required. He then goes to class and tells Arnest that he needs to talk to her which the latter agrees and tells him to follow her to her room much to the professor's futile protest. In Arnest's room, she offers him coffee and takes a seat, telling him that she's grateful for him keeping silence about the incidence with the sword and that she's willing to return the favor as long as it's something she's capable of doing however, Blade stops her saying that he's not following her.

Arnest asks if he's here to coerce her because she is the next head of the House of Flaming which Blade denies. He tells Arnest that he knows of the fact that the next head of the Flamings becomes the owner of the sword, asking her to tell him the full story. He mentions that he knows the sword very well and probably, it's whole story, saying that its intelligent and possesses a will of its own. He says that Arnest has not yet fully mastered the sword and thus it's curse still remains. Arnest agrees and tells him her story with the sword Asmodeus. She tells him about the sword's curse and Blade comments that she will never become like that. He then tells her that he knows a way to liberate her from the sword's curse as well as the rituals required to do so. Arnest tells him of her fear of repeating the massacre she made several years ago, but Blade nonechalantly says that if that happens, he'll just kill her, asking if she has any problem with his plan. Arnest says that she doesn't.

Blade takes Arnest to the Royal Library of Banned Literature and draws a magic circle on the ground then commanding Arnest to begin. As Arnest is being consumed by the sword, Blade reassures her by saying that he believes in her which the former returns.

Power and Abilities
Blade is very powerful, albeit only a glimpse of his power has been revealed so far in the manga, his power is described in the data graphics. Immense Strength: Blade is frightfully powerful, although not having the appearance to support it. Using only one arm, he's capable of taking down a dragon. It was also stated that he is so ridiculously powerful, the type of sword he uses does not matter.

Immense Speed: He is also very quick as seen in his initial encounter with Arnest and also against the Library Guards, which is further proved in the data graphic.

Inhuman Eyesight: Blade also possesses sharp eyesight, capable of seeing anything exceptionally clear. He can even see clearly up to 10 kilometers ahead.

Swordsmanship: He seems to have some mastery with swords as he's seen carrying one on his back all the time, and actually using one before (albeit being unable to measure down his strength). It is stated that regardless of the sword he uses, Blade remains powerful.

Equipment and Weapons
Though in most covers, Blade is seen carrying a sword around his back, Blade has only wielded one during training which he got from Arnest. It could be assumed that he currently does not have a go-to weapon yet.
