All My Secret Identities Came to Life

[Blurb]

The protagonist is an ordinary college student. One day, he suddenly gets bound to a System and must take on various secret identities, travel the world, and complete the System's missions.

The more he plays his roles, the more he feels that his secret identities have feelings of their own. Later, he learns that they are people destined to die in this world. The moment the protagonist fakes his death is the moment they die.

The protagonist refuses to go along with it. What does it mean, death that can't be undone? He won't accept it!

He escapes the point where he's supposed to fake his death and turns the tide, helping each of them escape their destined deaths. Then he returns to his peaceful college life.

Only to discover... the bigwigs he played are coming after him!

Worse still:

Gin realizes that her childhood friend has been acting strangely lately, always running off to the university;

Gojo Satoru and Geto Suguru realize their unhinged classmate has been ignoring them and sneaking off alone to go on dates at some university;

Oda Sakunosuke is so worried that someone is tricking his sickly younger brother that he secretly follows him...

The former secret identities: The three-year agreement is over. The Dragon King has returned!

The friends and family of the secret identities: Let me see what little vixen has caught his eye!

Protagonist: ???

Hey, don't come any closer!!!
