[Xystus]

Idol is actually a bitch flag raised. Looks interesting now, someone else gonna know about his futuristic stuff.

 

[MOKALI]

what a bitch

 

[HYBRID_BEING]

So, is he gonna regret pushing the button?

 

[DarkFlame]

that bitch (idol)... he should've just gone betting :/

 

[Jorelm]

Wait, how does she know it lets you travel back in time?

 

[acardoso]

@Jorelm she probably pushed the buttom herself

 

[Jorelm]

@acardoso but I thought it worked only three times? And he used the last go saving her.

 

[kkuroro]

do you use translations from Japanese to Spanish ?????

 

[Vergil]

Shoulda made that cash money son

 

[komikotaku]

hmm... how about the 3 times used?

 

[rgzmann]

Spoilers

 

[Badboll]

Her time when she used it would have been the 4th so there is no way she knew that. Plot holes!
MC used it 3 times

 

[acardoso]

@Jorelm maybe its 3 times per person, let's hope the author clarify this

 

[Wildfire_desu]

oh yes, the ultimate way to clog up the entire space-time with random fuck-ups - time travel!

 

[Kwijo]

Yeah, I'm with the plot hole camp. She clearly described it as a disposable item with 3 uses. If she hadn't said disposable, I might be on board with retconning "...per person" but it is hard to reconcile "disposable."

EDIT: Ahh... author explains.
