To be a hero

Season 1 episode 4

In the familiar forest, Izuku was rocketing after the blue western dragon, while Ddraig was face palming at his hosts stupidity. {izuku! You need to run!} not heading his partners warnings, Izuku smiled, looking up right at Tiamat, who now completely stood up, releasing a demonic roar, wings spread wide. "Alright, Ddraig! We might half to." Before Izuku could finish, he was rocketed away, with Ddraig wanting to defend his host, activated the balance breaker, that however made her even more enraged. "I do not know what your grievance is, but I will take you down!" With that, Tiamat leaped upwards, rocketing towards Tiamat, as large draconic wings spread out wide, and rocketing into her once more. Izuku then smiled, before hammer punching her in the back, causing her to go spiraling downwards and into the ground. Izuku was unhappy but things would be different.

Tiamat stood up, growling and spreading her wings. "I will end you host of Ddraig!" With that, she rocketed right towards her once more. Izuku then gave a low smile, but not before sending a draconic roar. He then sent a rough house kick right into her face, and then a punch which rocketed her to the side. The two charged in, engaging one another, as Tiamat went in with biting and claws, while the red dragon emperor was punching and kicking into Tiamat.

The O.R.C flew in to see, watching as Izuku was rocketed away with one of Tiamat's tail. She dove right on down, Dodging, Izuku grabbed the tail, before throwing her into the ground at a far distance, and appeared, foot on the head, fist aimed at her eye. "Are you done?" Izuku asked, as Tiamat groaned, before she did her best to nod. Izuku, knowing what she meant, did just that. He let her go. Tiamat then began to shine a bright red, before changing into a blue haired girl. "Since you hold Ddraig, I hate you!" She said, as Izuku then sighed. "Listen. Leave it. I know you hate it, but..." 

"But what! You want to kill me!, use me!" "No... I just want company. A family. My previous family was killed." Smiling, Izuku was quite unhappy. The heroes were present, and now? Izuku was smiling. He then proceeded to watch as Tiamat growled, saying, "Ddraig promised me that they would be together!" IUku sighed, and said, "I can do that. If you join yourself within the boosted gear, you can do just that." Nodding, Tiamat smiled and vanished before their eyes. 

"What just happened!" Rias states, but shook it off not expecting an answer, as they were transported home for the day. After arriving, celebrations happened. Cake was served. However, as they were watching, a Phoenix was watching them from the trees, as a certain man surrounded by woman chuckled to himself, saying, "soon, we will meat my love!" 

(Aa few days later)

Izuku went right off to bed. Scoffing, lying right on down thinking about what was going on. Izuku new Ddraig was completely asleep with Tiamat in his mind, while Izuku was wanting to sleep, but for some reason he was unable to do so. As things went on, a few seconds or so later, someone appeared in the bedroom. Rias Gremory. She had this desperate look in her own eyes. Izuku could not speak, as he was kissed by her. After the kiss, she just said, "take me!" Rias tried to kiss, but he covered her mouth, pushing her off gently.

"Why do you reject me! Am I not beautiful enough?" Izuku smiled, saying, "enough. Listen, you are beautiful, but if you want me to take you, I need you in the right side of your mind." After words, he saw her tear up, so Izuku proceeded to hug her right after covering her nude body up, as when she appeared, she stripped down nude. "Can you tell me?" Rias was about to talk, but that is when a magic circle appeared. Out stepped a certain girl with white hair in a maid outfit. "Graifia. Why are you here!" She states, as the girl said, "come on, Rias. Let us go!" Rias sighed, saying, "Fine, but I will show my self to whom ever I want!" Nodding, the two walked out, as Izuku sighed, lied down smiling. 

After that night, Izuku was summoned to the O.R.C. As he entered, he sighed, as Rias calmed down. Sighing, she said, "As I must say... I am engaged." She felt a certain magic appearing, as Rias then walked to Izuku, and kissed him. He kissed back, and that is when Riser appeared. "RIAS!!! HOW DARE YOU KISS A LOW BORN!!!" Riser rushed to attack, but was atopped by Graifia. Rias and Riser then began to argue, on which the two of them were being ignored by Izuku, who just stood up and began to walk away. That is when riser noticed. "How dare you walk out on me!" Riser shouts, as Izuku just looks at him. Sighing, Riser attacked, and that is when Izuku dodged, before he then sent a severe round house kick, rocketing him into the wall. "I do not wish to harm you anymore. Leave!" Getting out of the wall, he growled, looking at Rias. "Ten days!" Nodding, Riser teleported away, followed by Graifia.

Sighing, Rias said, "Go home. Pack the bags. We will begin to train!" That is when they nodded. Izuku was unhappy anyways, with the remaining heroes were quite happy, with what was going on. Izuku just grabbed his things and went right back, so they could begin the trip.

(A few hours later)

Izuku was walking right up the hill. Smiling, he continues to walk right on up that hill, walking side by side with Rias, who smiled. "Let's go!" Once at the top, they saw the manor. "Rias, I will train with you. I think we could grow even stronger in ten days." Nodding, Rias said, Koneko, I need you to focus on strength. Kiba, speed, akeno magic. Let's go." Smiling, Izuku grabbed Rias and they flew right to a nearby mountain and landed. "Ok, I will use scale mail. Use your destruction. Try use melee as well, understood." Nodding, they got in a stance, and Izuku entered his scale mail. 

{Welsh dragon balance breaker!} Izuku smiled, things that were ultimately happening, the remaining two of them charged in. Izuku nearly hit her, as she fired a magical blast of destruction. "I would have hit you in the chest or face." Rias nodded while a Izuku then said, "we have a lot of work to do... with only ten days, we half to center doing so." Izuku was smiling, as Rias attacked, and Izuku dodged, pinning her. "I win again." He got off of her, smiling. The heroes were happy now, as Izuku chuckled. They got ready, once again, before they attacked once more yet again.

After five days, Izuku pushed her magic to evolve. Rias mastered it. She unlocked a form of satanic destruction, earning a name of form of chaos. Izuku was happy with her. She evolved as a devil, becoming a pure avatar of destruction. "Alright, now for stamina. Run with me." Rias nodded, and the two of them began to run on forth.
