It seems the author of Tokyo Revengers is molding Takemichi to oppose Mikey and alter the future he sees.
In 2021, Tokyo Revengers surged as a hit. The author crafted a successful tale of time travel intertwined with street gang themes. Like Eren, protagonist Takemichi Hanagaki evolves from aimless youth to risk it all, accepting the dangers of time travel to change his loved one's fate. Along the way, he gains allies and seeks to alter their destinies.

In 2022, following Draken's death, Takemichi resolves to build a strong gang to stop Mikey from being consumed by street violence. Mikey won't stop, while Takemichi sheds his timid image to save those around him, especially his girlfriend Hinata, whom he loves and tries to alter her tragic fate.

Tokyo Revengers' 2022 manga shows the protagonist's bold strides. To confront Mikey and change the future, Takemichi may face death. This prediction arises from the idea that altering the past opposes life's natural order, potentially leading to death. Successfully changing Hinata's future death may demand the protagonist's own demise, hinting at a somber conclusion.

In summary, it's not uncommon for protagonists, even in time-traveling manga, to face hardships, even death. Perhaps the author uses Takemichi's fate to convey messages about life, effort, and the costs of altering nature. The clash between Takemichi and Mikey could conclude everything.
