Tokyo Revengers: Opposition

Perhaps there has never been right or wrong in this world. It's only a matter of perspective, and people have no choice but to claim they're on the side of justice and take part in the struggle for “justice.”

Parallel-world setting:

In another parallel world, Hanagaki Takemichi had completed his mission and was enjoying middle age, but he kept dreaming of strange scenes. One night, as if drawn there by some unseen force, he went to the place where Shinichiro had jumped into the river. He seemed to see a figure?!!

The figure looked just like Mikey, but was a girl. When she jumped into the river, Hanagaki followed her…

To his surprise, he transmigrated to another parallel world, one where two different people existed.

But Terano Yuko also seemed to have something she needed to protect, and none of these acts of “revenge” went perfectly.

But when the truth was finally revealed, Hanagaki Takemichi was numb at last…
