The Strongest Digimon Fighter

It's so confusing, I just finished reading the first few chapters, and sometimes there are several repeated plots in the same chapter. The segmentation of character dialogue is also not handled well, and it often feels incoherent.

Some of the characters are old philosophers and they are children. Except for the protagonist who is reborn, he is a bit mature. Others are not old-fashioned. Digimon is more youthful and passionate.
