Airu went up the stairs towards Romio saying that the one he is conspiring is Juliet Persia. Everyone was shocked by this. Airu then say that he was wondering why Romio leaved the dorm last night and he realized that is to celebrate Persia’s birthday with her. Since that failed he came here today. Romio told him it’s wrong but the students started to think they might be a couple. Persia told the Airu to stop putting stories to her and he should be ashamed being the Head Prefect. The White Cats back her up saying there is no way for Persia to betray them. He said that he have evidence. For one he found there was a Rosary in Romio’s room also his calendar has a circle on the date of Persia’s birthday. Persia said those could be lies and are not real evidence but Airu said otherwise. He showed them a Western Bra he found in Romio’s room. Cait laugh saying its sexual harassment. But he also have doubts in Romio and Persia. The two head prefects take them away for questioning.

The both of them pointed at their chest saying to came right at them. The two charged right away hitting each other swords and hitting each other’s chests.

Airy find it troublesome and decided to fight both of them at the same time. They find it unfair but Airu told them it’s a handicap considering Romio’s injury and Persia have a different physique. The three of them then take the fight outside since it was crowded. Persia attack from above but Airu managed to block it. Romio then push her away since make both of them argued.

Romio, Julio, and Airu 1, 2, 3 and 4 Edit
Airu have return home early. He was having breakfast alone until Romio open the door. He was surprise that he is here early and Airu explain that he already finished his prefect duties and return home before the storm comes. He then notice someone standing behind Inuzuka. The person introduce himself which is "Julio". Airu said he looks familiar. As before he could notice about Julio’s identity, his mother came running and hug him. Airu is being swept by her which make Julio surprise. Airu told Romio to come to dojo after breakfast so he could fix his slacker mind of his. The two are sparing while Julio, Shuna and their mother watch them. Inuzuka managed to gain some ground. He said he won’t be shaming the Inuzuka clan anymore. Airu smirk saying get a full of himself. After a while during their fight. They heard a noise coming from outside the house. They went outside to see what’s going on. They saw Shuna and Julio collapsed next to the main building. Julio said he’s fine but Shuna is not since a room tile hit her head. But that isn’t what Romio is more worried about. Everyone is staring at Julio which make him curious. Airu then ask him “Why are you here…?! Juliet Persia!”
Persia’s identity have been found out! Of all the people, it had to be Airu who found out! He slowly to understand why. He’s conclusion was right was correct. That these two are in a relationship! Airu carried Shuna and lend her to his mother to bring her inside. When the two of them left, Airu want to hear Romio’s excuse. Romio apologies for keeping a secret from him but he told Airu that he’s serious about this. However, Airu said that it’s no concern to him whenever his serious or not. The two nations are in war right now, the Inuzuka clan is a family politician. If society found out that the two sons is involved in an affair with a woman from a hostile nation. They will lose trust on them and the Inuzuka clan will be reduced to nothing. Romio convince that he won’t let that happen. He will change this world by first becoming a Prefect and change the academy. Before he could continue to explain, Airu grab his Kimono and said that that’s all a gamble and he’s out of his mind. He thinks that Romio wants to destroy the Inuzuka clan. He dragged him to the shed and Persia follow him. He give Romio only one choice. Either break up with Persia or leave the house. He only have tonight to answer. He leave the two alone for now.
Both Romio and Airu are outside with their school uniform. He still refuse to break up with Persia but want to protect the clan as well. If he wins he want his brother to let him walk his own path. The two of fight with purposed. Airu is beating his brother without a sweat. But Romio still haven’t given up. He will beat Airu and change the world. They continued fighting but Romio starting to block and dodge his brother’s attacks. Airu is wondering why he haven’t given in. Persia yelled out at Romo after Airu punch him. Airu look at Persia and then got punch back by Romio. Airu started to know why he haven’t given up since he is against breaking up with her this much. But Romio said that’s not all. Romio isn’t like Airu’s current self. He admits that he think he was cool back then but since he only wants to protect just the clan, he isn’t afraid anymore. Airu was pissed saying he doesn’t know anything about him. He punch Romio’s face, but he look back at him with the same eyes as him back then. Romio then grab Airu’s tie and head-butt Airu’s head. Romio collapsed first but Airu was standing until he said, “The one... with the thick head… Is you! Romi… o…” He then collapsed as well. Romio then get up once again which make Airu surprised. He came up to him saying he always hate and was afraid on him. He never notice how hard he work to protect all of them. But he told him that’s enough. He will become strong to protect mother, Shuna, him and even Persia. He thank Airu for everything. Airu then realize something. How.. Why.. When.. did he forget the things he truly want to protect the most. Romio believe he’s being selfish but he want Airu to trust him to change the world one day. Airu told him that’s enough and he have lost.
The next morning, Airu woke up in his room with his mother there. She apologize that she was being weak and Airu have to do all of her job fr him. But from now one she will do her best. Airu told her to do as she wish. His mother was happy that she hug him right away. Airu was about to have breakfast but heard a noise in the living room. Airu enters the living room ask what’s the all the racket. Shuna see that Airu is injured as well and ask him if a blonde woman did it to him. Romio was worried but Airu said there isn’t any blonde spices here. He came behind Romio telling him not to misunderstand. He haven’t approve their relationship just yet. They all have breakfast after that.

Awhile ago, Airu ask the White Ctas Prefect a favor for the firt time. He explain his favor. He want to have a exhibition match bwtween the 3rd year and 2nd year. They will soon retire and there is something he want to teach them before that happen. It's not something he could use with words but it's something he want them to understand.

He was about to say he will surpassed him but Rex Charge and move Scott out of the way. However, Scott managed to buy some time to get the other second years to block Rex. Rex then passed the ball to Cait. Cait dodge every one of his opponent’s while saying they still don’t understand the meaning behind the match. Romio was wondering what he meant by that. Aby tried to blocked Cait but he was stop by Somali who was hugging him. Cait then later insulted Aby which make him depressed but later been in courage by Somali and put him back in the mood. With no other choice, Cait use his secret move called the “Ball” hiding. He lift the ball up and bring it back down and make it vanished. But everyone could see it’s in his pants. Sieber then hit the ball out of his pants which hurt Cait’s crutch. With Cait unable to move for a while, this is the second year’s chance.
Everyone is in the rose garden and Sieber have the ball heading to the goal. Hasuki was about to get the ball but Sieber pass it to Kochou. They almost arrive at the fountain. Leon can tell that fighting the 3rd years was a loss casue.Airu then ran next to her saying she just doesn't belive in herself. She is just a bother and should just leave. Kochou pass the ball to Airu and he charges in. But Inuzuka was blocking him upfront. Airu push Romio aside but after he did, Persia was behind Romio from a blind spot. She took the ball from Airu saying their counter attack begins. Persia can’t go forward since it’s been block by the third years. She then ran to the left to flank them. When Romio is with Airu, he told him that he finally realize the reason of this match. Airu then push Inuzuka to the side once again.
The second years disappeared of the map somewhere. They are hiding somewhere so they all went looking for them. After awhile Kochou and Teria found them and aiming to get the ball from Persia. Scott throw Romio at Kochou and Teria for a decoy. They came out of the forest but Rex was blocking them. Persia passed the ball to Hasuki and ask Scott to bend down. She then use him as a stepladder to break free. Aby then grabbed the ball from Hasuki saying he should have it. Scott also join in trying to get the ball from the both of them. Airu look stare at them with disappointment attack Scott who have the ball. But he was saved by Romio. Scott asked why would he saved him. Romio explain to everyone that they are prefects. They have the same ambitions to change the academy. As long they have same goal in mind, there shouldn’t be a problem working together. When he was taking, Cait steal the ball from Scott and ran off. As the second years are chasing him, they receive a cheer from both Black Dogs and White Cats. The school have slowly started to change.
Airu and Cait were heading to the goal. They notice that the 2nd years are not following them and probably given up. Then Romio pop out of the manhole and steal the ball from Cait. He then throw it a far where the other second years will be. They were about to grabbed it but see that Sieber and Rex won’t allow it. However, Hasuki and Aby work together to stop Rex. Leon’s job is to stop Seiber. She think of her weakness and said “Bear Panties” which make Seiber stop running. Persia stop both Kochou and Teria while Scott is charging to the goal. Scott made it through the main building almost reaching the goal. But behind him was Airu who won’t allow him to get away that easily. Airu was about to steal the ball from Scott but he did a back pass and give it to Romio. Airu ask Scott how did he know that Romio was behind him. Scott replied that wherever he goes, Romio will come chasing him. Everyone was cheering for Romio. He made his final move to throw the ball but he tripped. However, the ball still managed to hit the third year’s goal. The second year prefect won! Airu expect him to finish it well but proud of the ending. He will be expecting more from him in the future.
