Can I use your bathroom?

Hikaru wanted to use Laylah  to defeat the other protagonists. That was also the reason he accepted her request to stay here.

Although he didn't know if Laylah would become his ally, he wanted to try.

Anyway, Laylah is also a main character, and he is a villain, if he fails, everything returns to the starting point. He and Laylah will be enemies like every other novel.

If he succeeds, he not only has a terrible ally, but that ally can help him destroy the other main characters.

However… he also didn't want to put all his eggs in one basket. He needed a backup plan.

Hikaru began to try to remember what he had read in the novels "Apocalypse: I own the Panara Box" and "The Apocalypse Encyclopedia".

However, everything was in vain because most of the great items or good opportunities only appear when the apocalypse hits.

So, none of those things have appeared.
