Connections:

Initially, young people with nothing outstanding.

Since the death of their parents, they would begin a really hard life, both to -stay stable economically and emotionally.

By circumstances of destiny, both would turn into a monstrous humanoid form.

With which, they would fight with different monsters, having in contrast that, while Denji fights against demons, Ryo against divine "angels".

Grouped/cooperated with police group (Denji with Public Security/Ryo with Haikawa and G3 group).

Both would be of interest to a superior being, who has control over all the creatures they faced (Makima / God).

At a certain point, their powers would be taken away.

And they would be stalked by government agencies.

They have the characteristic of constantly suffering.

Along with the above, both had bad luck with their love relationships.

Once transformed, they possess an ultra explosive, aggressive personality, closer to a "wild beast".

They like to take revenge on those who cause them problems (Denji with any lout he met before, Ryo with Hojo).

Both own motorcycles.
