My Hero Academia revolves around a simple conflict rooted in the history of All For One, the main antagonist, and the powerful One For All Quirk, which the protagonist Izuku "Deku" Midoriya inherits. The One For All Quirk, passed down through generations, traces its origins back to Yoichi Shigaraki, the younger brother of All For One.
Yoichi and All For One, born as siblings, took divergent paths in the My Hero Academia storyline. Yoichi embraced goodness, while All For One descended into tyranny and villainy.
Despite his powers and resources, All For One never let go of his hatred and selfishness toward Yoichi. He always claimed that his brother was getting in his way, but the real reasons lie in his obsessive nature.

All For One and Yoichi were twins. All For One had a Quirk that allowed him to absorb other people's abilities, making him stronger quicker. Meanwhile, Yoichi was constantly malnourished and weakened, highlighting the difference in mentality between the two characters.
During his battle with Katsuki Bakugo in the final War arc, All For One had a flashback. The flashback revealed that he did not care for his brother's well-being and saw him as a possession. Despite mistreating him, All For One gave Yoichi the Quirk that would eventually become One For All, mostly out of pity.
Yoichi and All For One's impact on the storyline
Yoichi utilized his Quirk to establish a bond with Kudo, causing All For One to feel resentful as his brother chose a stranger over him. This showcased All For One's possessiveness, seeing Yoichi as his possession and leading to his animosity towards Kudo, the second user of One For All, during their confrontation with Bakugo.

There is a strong argument to be made that All For One and Yoichi are the two most important characters in the entirety of the My Hero Academia manga. The entire conflict of the series began with the two of them many decades ago and both have been building their powers ever since, which has led to the final battle between Deku and Tomura Shigaraki at the moment.
They are also very good representations of their abilities, with All For One's Quirk focusing on stealing powers from other people without their consent while Yoichi's One For All only grows through the lives and experiences of each new user. It is a very good example of who they are as people, which has been fairly consistent since they were introduced.
All For One's obsession with Yoichi stemmed from his inability to control him, leading him to desire the power of One For All. Obtaining this Quirk symbolized victory over his brother and achieving the triumph he yearned for.
Final thoughts
All For One had a strong obsession with Yoichi in My Hero Academia. He saw Yoichi as his own possession and wanted to keep his younger brother under control. However, Yoichi decided to leave when Kudo, the second user of One For All, showed up. This only made All For One's obsession with Yoichi even stronger.
