Izuku Midoriya, known as Deku, was not an ordinary student of U.A High School. He was different, not only because of his extraordinary intelligence but also because he had four quirks. The first one was toxic love.

He would use this quirk to manipulate people's emotions, making them fall in love with him and do his bidding. It was a potent ability but one that he used sparingly, knowing the dangers it could pose.

His second quirk was called Demon's Fury. When he activated this, his body would radiate a dark aura, and his physical strength and speed would increase exponentially.

The third quirk was the Staff of Fear, named after the Bionicle villains, the Rahkshi. This quirk allowed him to summon a spectral staff that could inspire fear in his opponents.

His fourth and final secret quirk was a godlike one known as One For All. It was the same power that All Might had, but much stronger, powerful, and effective.

Ochako Uraraka was Deku's girlfriend and best friend. She was the one person who knew about his secret quirks and was always there for him.

Deku's greatest enemy was none other than All Might. He was jealous and angry at Deku's debut, knowing that his secret quirks were dangerous.

All Might also knew that Deku's fourth quirk, One For All, was the same power he had. However, it was much stronger and more powerful in Deku's hands.

The showdown between All Might and Deku was inevitable. The two of them faced off, their powers clashing in a battle of epic proportions.

Deku was able to defeat All Might, using his four quirks to overpower the once unbeatable hero. All Might screamed in agony and rage as he fell.

All Might's spirit was banished to a place where the devil smiled at him for his defeat and death. The demon took his quirk and spirit away, leaving him to face his punishment.

Deku stood victorious, his heart heavy with the weight of his actions. He had defeated his enemy but at what cost? The victory was bittersweet.

In the aftermath, Deku was hailed as a hero. But he felt more like a villain. He had taken a life, even if it was to protect others.

Ochako, however, was there for him. She held him, comforted him, and reminded him of why he had to do what he did. She was his rock in this storm.

Deku knew he had to keep going. He had a responsibility to use his powers for good, to protect those who couldn't protect themselves.

He had to carry the burden of his actions and the power he held. It was a heavy burden, but one that he was willing to carry for the sake of peace.

In the end, Deku had to accept that he was not just a hero, but also a protector. His power was not just for defeating enemies, but for protecting the innocent.

He had to learn to balance his power and his humanity. It was a difficult task, but with Ochako by his side, he knew he could do it.

Deku's journey was far from over. There were still many battles to fight and many lives to save. But he was ready.

He had the love of Ochako, the power of his quirks, and the determination to make a difference. He was Deku, the hero with the four quirks.

In the end, Deku's story was one of power, love, and ultimate sacrifice. It was a tale of a hero who had to discover the true extent of his abilities.

It was a tale of a hero who had to face his greatest enemy, make the ultimate sacrifice, and come out stronger on the other side.

It was the story of Izuku Midoriya, known as Deku, the hero with the four quirks. And his journey was just beginning.

And so, Deku continued to fight, to protect, and to love. He was a hero, not because of his quirks, but because of his heart.

And that, in the end, was the most powerful quirk of all.
