Yuudai Moroboshi

"Good food is good motivation, y'know? So just take the day to rest up, and then meet me in the match tomorrow in your best condition, better than you've ever been. Provin' my strength by defeating an opponent at their strongest—now that's well worth the meal I treated!"

- Yuudai Moroboshi

Yuudai Moroboshi is a third-year student in Bukyoku Academy and the previous winner of the Seven Stars Sword Art Festival known as the Star of Naniwa. A lot like the previous year, he participated as one of the three representatives of his school in the current festival.

Appearance
Yuudai is a handsome young man with blonde hair and green eyes. He is usually seen in his school uniform and wears a hachimaki.

Personality
Yuudai is a cheerful, talkative, straightforward young man. Yuudai is modest enough to not underestimate others and doesn't feel he should be called the Seven Star Sword King because the A-Rank Ouma Kurogane didn't participate in the previous Seven Stars Sword Art Festival.

Like Ikki Kurogane, Yuudai is very strong willed and hard working when it comes to whatever goals he sets for himself and doesn't give up until he reaches them, no matter how hard it is. This was proven by the fact he was able to make it through his hell like rehabilitation and go on to become the Seven Star Sword King. Because of these traits, Yuudai is seen as a home town hero and is very well respected by almost everyone who knows him personally. He also seems to be very tactical in battle as he came up with very clever ways to try and combat Ikki's movements even in his most dire of situations.

History
Even during his childhood, Yuudai grew quite famous, participating in Japan's Little League. In his primary school period, Yuudai was involved in a severe accident that almost left him crippled and had to retire as a Knight for four years. This leads to Yuudai's sister Koume Moroboshi, blaming herself for what happened to Yuudai, which resulted in her being traumatized to the point she was unable to speak. Because of this, he underwent rehabilitation with the help of Kiriko Yakushi. After hard work, Yuudai finally got better and even won the 61st Seven Stars Sword Art Festival against Byakuya Jougasaki. He also challenged and beat opponents such as Touka Toudou in the semi-finals of the Festival. After his victory, Yuudai was considered to be part of the Golden Generation, the three strongest students of Bukyoku Academy, also including Byakuya Jougasaki and Momiji Asagi.

Party Crashers
Yuudai is seen defending Ikki and confronting Yui Tatara, who had tried to severely injure Ikki's sister with sharp metal blades in the meat Shizuku was about to eat. The battle between Yui and Yuudai never proceeds as other representatives come into the confrontation causing Yui to leave in shame. Yuudai then introduces himself to Ikki, his first opponent in the Seven Stars Sword Art Festival.

Dinner and Confrontation
Yuudai meets Ikki, Shizuku, and Nagi and invites them to his family restaurant, Ichiban Boshi, to which they accept. During their time at the restaurant, Yuudai is unable to join them as he is busy helping the family with the restaurant.

After Ikki and company had left, Ikki gets attacked by Ouma, with Yuudai eventually coming to help him. Yuudai is seen stopping Ouma's Kusanagi attack on Ikki, by using his Tiger Bite to completely stop Ouma's powerful attack. Ouma then decides to leave and Yuudai takes a heavily injured Ikki to the hospital.

Battle of Kings
Yuudai, the next day, confronts his opponent Ikki at the Seven Stars Sword Art Festival. The fight begins and Ikki tries to get the upper hand but is badly outmaneuvered and outwitted by Yuudai as Ikki takes heavy damage by the combination of Sanrensei, Houkiboshi, and his Noble Art Tiger Bite which nearly destroyed Ikki's device.

Yuudai, however, was nearly beaten by Ikki who was able to use his fourth secret sword technique to create an after image, causing him to be able to get passed Yuudai's spear, however Ikki was unable to land the final blow allowing Yuudai to hit Ikki with the back of the hilt of Yuudai's spear.

Yuudai then tries to finish off Ikki but senses something dangerous within Ikki, this is proven right as Ikki finally realizes that his subconscious was trying to use Edelweiss' technique all along, which he picked up using Blade Steal in their last meeting. Yuudai is then quickly overpowered by Ikki and his new sword technique.

Yuudai is then seen badly cut up by Ikki's barrage of attacks that he could not possibly keep up with, causing his sister Koume, who was in the stands, to finally call out to him and cheer him on.

Yuudai then shows his final hand and tries to mess Ikki up by throwing his spear at him knowing he would not be able to dodge as Edelweiss' technique's one major flaw was that if taken by surprise the user could not stop to dodge. However because Ikki believed that Yuudai would never give up, he could see through this trick and used his after image sword technique to trick Yuudai and then slash to finally put down the Sword King once and for all, giving Ikki the win. Yuudai is then carried off on a stretcher after giving Ikki some encouraging words.

Conclusion of the First Match
Yuudai later meets Ikki and Nagi in the bathhouse, where he orders Byakuya Jougasaki to stop teasing Ikki. Ikki and Nagi then leave, as they think Yuudai probably wants some time on his own after his loss.

Yuudai later is seen speaking to Byakuya, before the latter's match against Ikki. Byakuya proclaims that Ikki won't use his Ittou Shura or Ittou Rasetsu, as he will need them for his third match on the same day. Because of this Byakuya believes he will defeat Ikki in 23 moves. Byakuya is proven wrong though as Ikki uses Ittou Rasetsu, and wins in 0.8 seconds.

Tournament Final
Yuudai and many other students help Ikki train for the upcoming finals of the Festival, where he will face Stella Vermillion. Yuudai has a mock battle with Ikki, not using Tiger Bite due to not wanting to damage Ikki's Device, which would tamper with the upcoming finals. Despite this, Yuudai puts up a good fight, initially having the advantage due to his faster Sanrensei. Ikki, however, defeats Yuudai by minimizing unnecessary movement and cut off any unnecessary senses, adjusting to Yuudai's attacks and defeating him.

Yuudai is later seen watching the finals of the Festival, between Ikki and Stella, which Ikki wins, becoming the new Seven Stars Sword King. He later attends the awards ceremony.

The Festival Is Over
After the Festival Yuudai is seen talking with Touka Toudou, about their futures, and how he is thinking about going to China, to fight in the God of War League. They later promise to have a rematch in the KOK A-League someday.

Abilities
Master Spearmanship: Yuudai is an extremely skilled and proficient spearman, able to defeat a dangerous opponents such as Touka Toudou, who was feared in close-combat due to her Raikiri, albeit through staying outside of its range due to the natural long reach of his spear. His sheer power, speed, accuracy, and skill was able to cause even a well-rounded martial artist and swordsmen such as Ikki to become impressed several times in their first match in the Seven Stars Sword Art Festival.
 * Happo Nirami (八方睨み, lit. Glare in All Directions): A defensive stance that Yuudai employs. It is praised as being without openings from all directions by Ikki.
 * Sanrensei (三連星, lit. Three Linked Stars): Yuudai's high-speed spear technique which involved striking three points at once. The technique's speed is lowered when Yuudai uses Houkiboshi or Tiger Bite with it. At its absolute speed, Ikki mentioned it being like a meteor shower.
 * Houkiboshi (帚星, lit. Comet): A homing-thrust technique which involves the movement of the wrist. Yuudai uses this technique by tricking his opponent into stepping into his range by using on thrust in his move and traps them with Houkiboshi. Avoiding the technique can be extremely difficult and blocking it is also made dangerous due to Yuudai's ability to destroy a Device of a Blazer.
 * Blind Spot Thrust: A thrust that attacks through the opponent's blind spot so that it is invisible to the opponent.

Immense Speed: Yuudai can move and strike at such amazing speeds that most people watching him fight can't even see most of his actions. His strikes are even able to temporarily corner Ikki, who used Edelweiss' technique to improve his speed.

Immense Stamina: After having made it through his hell like rehabilitation, Yuudai has gain incredible amounts of physical and mental endurance.

Keen Intellect: Yuudai is well-known for his cunningness in battle, capable of misleading his opponent's into a false sense of confidence under multiple layers of traps to defeat them. He can also figure out the weaknesses in a person fighting style and make plans on how to best deal with them. He was able to see through Ikki's intention when using Dokuga no Tachi and make a trap of his own to counter the technique, although he had never seen that technique before. Yuudai also has shown being able to adapt and improve his tactical skills, being capable of seeing through Ikki's Shinkirou after seeing it once.

Magic Destruction: Yuudai's Blazer ability allows him to destroy other Blazers' magical abilities. He can easily break through both Device and Noble Art of even an A-Rank Mage-Knight. This gives him an advantage against Mage-Knights who mainly fight using their Blazer abilities, although the ability is less useful against Blazers who utilize mainly martial arts.

Device


Tora-Ou (虎王, Tiger King): Yuudai's Device. It takes the form of a yellow spear.
 * Tiger Bite : Yuudai's trademark Noble Art, it creates a Golden Tiger made from magic power and can devour almost anything in its path. Also due to its properties of being made from magic power, the Golden Tiger can devour the opponent's Device and Noble Art to power up but the tiger is unable to cause physical damage in return.

Trivia

 * Yuudai's techniques and nicknames are themed around stars. Even the kanji for "boshi" (星) means star.
 * Yuudai is the second person after Kaito Ayatsuji who lost to Kuraudo Kurashiki at the last moment due to his Marginal Counter while leaving him wondering what would occur if their last technique landed.
