Berserker (Quiver Bits - Yamato)

Takeru Yamato, Class Name Berserker, is a Berserker-class Servant contracted with Misu Mujika in Quiver Bits, as well as her eventual boyfriend.

Background
Berserker's True Name is Yamato Takeru (though he prefers the order Takeru Yamato), a Demi-Servant human fused with the Heroic Spirit Yamato Takeru. His background remains the same as it did in the canon; Takeru was born in Kagoshima Prefecture but moved to America at the age of 11, where he became a youth American football star nicknamed Eyeshield 21, before returning to Japan at 13 years old. When he was 16 he first discovered his Domination origin, and began to experimentally try and use magecraft on his own outside games.

At 18, just after graduating Teikoku, he was sent a notice from Chaldea, who had taken notice of his unique morale-based magecraft. He hesitated but decided to go. It was here the accident happened, Misu being the only surviving potential Master. Takeru had to accept the Heroic Spirit of Yamato in order to live on. He became Misu's Servant alongside Mash. He proved to be an immensely powerful Berserker, only rivaled by the likes of fellow Demi-Servant, Seijuro Shin.

After being thrown into the Grand Line alongside Misu, Seijuro and a few other Servants, Takeru is the first to calm down and assess the situation. He is also the second of the group to be given a bounty, after Misu.

Appearance
Takeru is a handsome young Japanese man with wavy black hair and grey-gold eyes. He has taller than the average human on Earth, but is of a standard height in the Grand Line. He has a muscular build, long legs and a strong posture. His skin is slightly tanned, and he has select scars on his arms.

As an ordinary human, Takeru often wore a simple dark jacket and long-sleeved tight black shirt with dark pants and Converse shoes. After his transformation into a Demi-Servant, Takeru can be seen wearing a bastardized version of traditional Japanese robes

Personality
Takeru is a friendly, optimistic and honest person by nature. He is blunt and rarely minces his words, but is not the same kind of blunt as Seijuro. Takeru is much more self-aware, and conscientious and considerate of others. He wears his heart on his sleeve and rarely gets angry, usually taking things in level-headed and easygoing stride. He is generally kind, but is very blunt, brutally honest and straightforward, something he sometimes uses to spite people. Whether or not this is fully intentional isn't entirely clear, but it seems to be.

Rather than being prideful to the point of arrogance, Takeru radiates confidence that he will never lose. He is usually seen smiling calmly. Takeru has a strong respect for his friends and teammates, and firmly believes in team effort and cooperation. He seems to have a keen understanding of others and can think quickly and effectively under pressure.

Relationships
Misu Mujika


 * Takeru first met Misu several years ago while in America, when she was playing for Phoenix Middle School's basketball team. She was friends with Shun Kakei and went to watch the game. She was allowed on the field as a substitute manager, and wanted to check on Shun. She acknowledged Takeru as the one Shun kept talking about, and lamented they weren't able to meet under better conditions.
 * They encountered each other once more at Chaldea and he was thrilled to see her, saying how impressed he was with her talent and skill as a basketball player. She shot back by complimenting his speed, balance and power. He found her cute and it seemed the feeling was mutual, though neither acted on it.
 * Once Takeru became Misu's Servant, he had fun teasing her for how flustered she got whenever he called her "Master." Their relationship eventually evolved from there, however, and they became very close. They finally acknowledged their individual feelings and while Misu's behavior remained largely the same, Takeru became much more talkative and engaging. He was the only one who noticed her being much softer with him and became confident she returned his feelings. After their successful battle to chase off Blackbeard, she confessed, and he happily accepted.
 * They are best friends and trust each other immensely.

Abilities
Takeru is something of a miracle being. He was not engineered or designed to have an especially strong set of Magic Circuits and was instead born with them. Because this was a natural occurrence and not something imposed on his body by experimentation and genetic engineering, his life-span has not been set to a low number like it had been for fellow Demi-Servant, Mash Kyrielight. Since awakening Yamato, Takeru's already physically superior body became even more powerful.

Class Skills

 * Madness Enhancement (D- Rank): The Saint Graph itself has changed into a Berserker, but the rating of the assigned Mad Enhancement skill is low. Mutual understanding through language is wholly possible.
 * Succeed Phantasm (? Rank): A unique Skill that only Demi-Servants possess. One of the Skills that the possessing Heroic Spirit owns is inherited and sublimated in a self-taught manner. In Takeru's case, it is "Divine Presence," which greatly enhances his intuition, instincts and reflexes. Combining it with Kenbunshoku Haki grants Takeru abilities similar to the highest awakening level of Kenbunshoku.

Personal Skills

 * Caesar's Lead: A derivative of the Caesar's Charge technique he developed while playing gridiron. An offensive-oriented ability that grants a significant attack buff to all Servant allies, and helps him recover some stamina and mana.
 * Absolute Prediction: An ability for defense and evading buffs. Takeru's mental fortitude and level-headedness are converted into a protection of all Servant allies and apply a massive attack buff to himself.
 * Combination of Divinity: A skill that allows Takeru to draw from Yamato's power briefly and makes his own skin impenetrable for a short period of time.

Noble Phantasm
Takeru wields a double-sided ancient Japanese sword. This sword is the Kusanagi no Tsurugi, so he uses it as rarely as possible out of respect for the tradition of no one ever seeing the Imperial Regalia of Japan. However, as commented by Mihawk, it possesses the power of one of the 21 Great Grade Swords, possibly the 12 Supreme Grade Swords. It sends projectile slashes whenever Takeru pleases, each one's power proportionate to Takeru's mental fortitude and stamina. It is possible to wield this sword using nearly any style. After meeting Roronoa Zoro, Takeru is inspired to create his own huge twisters and does so in his first try, surprising Zoro. Takeru's natural intuition and analytical ability combined with Divine Presence and the nature of Kusanagi no Tsurugi allows him to learn new techniques nearly instantly after seeing someone else perform them.
