Introduction to Deku’s Journey:

In the first three episodes of My Hero Academia, we witness Deku's unhesitant acceptance of the All Might Quirk. However, its overwhelming strength presents a significant challenge for him to harness effectively.

Why Does Deku Need Training?

As we see in the opening episodes, despite Deku's overwhelming desire to become a hero like All Might, the power of the One For All Quirk is too great for his body to control immediately. All Might's training is crucial in helping Deku transition from a hopeful hero wannabe to a capable hero ready to wield the Quirk responsibly.

All Might's Training Begins

One of the central themes in My Hero Academia is the idea of training. Building muscles, not just physically but also mentally, is a defining characteristic of heroism. All Might, recognizing the immense power at play, decides to train Deku as soon as possible. The urgency is clear — without this preparation, Deku's body would simply be unable to handle the energy unleashed by One For All.

All Might stresses, 'He should train his body to the limit and beyond to accommodate such a powerful Quirk. Otherwise, it would be almost certain that the arms would rip off.' This statement underscores the gravity of the situation and the intensity of the training Deku must undergo.

Deku's desire to accept All Might's Quirk is profound and genuine. He dreams of becoming a hero, admired and respected, following in All Might's footsteps. The magnitude of this goal is clear from his actions and interactions with All Might. He shows unwavering dedication, determined to absorb All Might's power and become a worthy hero.

Control Over the Quirk

However, the Quirk also comes with significant control issues. As All Might explains, 'he was overflowing with energy because he was barely strong enough.' This statement highlights the overabundance of power that Deku is experiencing and the need to build up his strength further. The training isn't about just physical enhancement; it's about developing the mental and emotional resilience needed to handle such extraordinary capabilities.

All Might’s guidance is pivotal for this process. He not only helps in physical conditioning but also in mentoring Deku on the psychological aspects of heroism. Understanding the weight of responsibility and the mental fortitude required to wield such power is as crucial as the physical training.

Conclusion

Ultimately, Deku’s journey with One For All is both a personal and a collective awakening. It is a lesson in discipline, perseverance, and the importance of training. From his initial acceptance to his later struggles, Deku's path is a testament to the power of hard work and dedication. His ultimate goal remains the same — to become a great hero, not just in body but in spirit.

All Might's training is, therefore, not just about physical strength but also about the broader journey of becoming a true hero. It is through this training that Deku will learn the true essence of heroism and the responsibilities that come with it.
