Yuudai Moroboshi

Yudai Muroboshi is a student from Bukyoku Academy and the previous winner of the Seven Stars Sword Art Festival. Like the year before Yudai participates as one of the three representatives of his school in the Festival.

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

Personality
Yudai is a cheerful, talkative, straightforward young man. Yudai 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, Yudai 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, Yudai 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
During his primary school period, Yudai was involved in a severe accident that almost left him crippled and had to retire as a Knight for 4 years. This lead to Yudai's sister Koume Moroboshi, blaming herself for what happened to Yudai, which resulted to her being traumatized to the point she was unable to speak. Because of this Yudai underwent rehabilitation with the help of Kiriko Yakushi. After hard work, Yudai finally got better, and even won the 61st Seven Stars Sword Art Festival. He also challenged and beat opponents such as Tohka Todo in the semi-finals of the Festival.

Party Crashers
Yudai 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 Yudai never proceeds as other representatives come into the confrontation causing Yui to leave in shame. Yudai then introduces himself to Ikki, his first opponent in the Seven Stars Sword Art Festival.

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

After Ikki and company had left, Yudai 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 Yudai takes a heavily injured Ikki to the hospital.

Battle of Kings
Yudai, the next day, confronts his opponent Ikki at the seven sword art festival. The fight begins and Ikki tries to get the upper hand but is badly out maneuvered and out witted by Yudai as Ikki takes on heavy damage by the combination of Sanrensei, Houkiboshi and his Noble Art Tiger Bite which nearly destroyed Ikki's device.

Yudai 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 Yudai's spear, however Ikki was unable to land the final blow allowing Yudai to hit Ikki with the back of the hilt of Yudai's spear.

Yudai 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. Yudai is then quickly overpowered by Ikki and his new sword technique. Yudai is then seen badly cut up by Ikki barrage of attack 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. Yudai 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 Yudai would never give up, he could see through this trick, and used his after image sword technique to trick Yudai and then slash to finally put down the Sword King once and for all, giving Ikki the win. Yudai is then carried off in a stretcher after giving Ikki some encouraging words.

Conclusion of the First Match
Yudai 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 Yudai probably wants some time on his own after his loss.

Yudai 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.

The Finals of the Seven Stars Sword Art Festival
Yudai is later seen watching the finals of the Festival, between Ikki and Stella, which Ikki wins, becoming the new Seven Stars Sword King.

The Festival Is Over
After the Festival Yudai is seen talking with Tohka Todo, about their futures, and how he is thinking about going to China, to fight in the God of War Tournament. They are shown having a rather close relationship.

Abilities
Master Spearmanship: Yudai main form of combat next to his Noble Arts. His well-honed skills with his Device allowed him to defeat dangerous opponents such as Tohka Todo. This feat made more impressive because he was able to keep himself out of Tohkas' Raikiri range through out the match. The sheer power, speed, accuracy and skills he possesses has caused even a well-rounded martial artist of Ikki Kurogane's level to be greatly impressed many times during their first match. Magic Armor: Yudai is capable of surrounding himself with his own magic, forming a sort of armor. This armor though is not as durable as Stella's Empress Dress, and it also forces Yudai to completely give up on attacking, thus rendering it a purely defensive technique.
 * Sanrensei (三連星, lit. Three Linked Stars): Yudai's high-speed spear technique which involved striking three points at once.

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.

Magic Destruction: Yudai'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.

Device
Koou (虎王 literally, Tiger King): Yudai's Device. It takes the form of a yellow spear.
 * Tiger Bite : Yudai's trademark Noble Art, it creates a Golden Tiger made from magic power and can devour almost anything in it's path.
