Anime Crossover: I Have a System to Back Me Up

What's written is so messed up that I can't understand it. Why is it still in the first person? Sometimes it's first and sometimes it's third.

The cover is the game Beautiful Water World

Since this cover is used, it must be worthy of this book

The official name now should be Deep Sea Trek.

Will the male protagonist meet the male protagonist in the game when he returns to the world of Deep Sea Trek in the future?

And there are alien anti-aircraft guns in the game. To disarm the anti-aircraft guns, they must be turned off. And it requires blood analysis. In the game, the male protagonist is infected with the Jkara virus and cannot turn off the air cannon.

I became a little interested when I saw the cover of Beautiful Water World... But unfortunately, I am a student who is not allowed to play computer, so I can only learn about it by watching videos... It is said that there is a deep pit that is ** meters deep (the boat can be made up to ** meters, and there is no limit on people and limited oxygen)

What I hate the most is that the male protagonist is a bastard. You might as well just become a transvestite or a tj.

Why is there "I" in the middle? Isn't it better to remove it?

Regarding the person issue, it's a bit strange to use the first and third person together, and there are no illustrations.
