It wasn't these two options that left me in doubt.

But the third option.

If I kill Shinsen here and now, won't it be all over?

A dark nebula, once unreachable, is now within range. For this
moment to come, we fought their organization to this day. Isn't
that why I followed the clues Johnny left behind and came all the
way here?

Eliminating the last enemy.

But... can I do it?

How can I do it?

"Your eyes have changed."

Shinsen's words made my heart skip a beat.

At the same time, a shadow was cast on Shinsen's face.

"Unfortunately, even if you get rid of me, the plan will not stop.

Didn't I say it just now? Everything has been arranged." He said as
if he just read my mind. "By the way, I can tell you that because of
your efforts, the size of our organization has indeed shrunk, and
now the remaining people are pawns who only follow orders
blindly. However, it also means that the organization has become
a rational apparatus. It is a device with a built-in program that
offers revenge as a game. That means, even if I am gone, the
organization will continue to operate as programmed, and the

'Black Challenge' will continue as usual."

"That’s……"

"So there’s no point in killing me here."

"Oh really? At least no one will do anything to Kirigiri-chan, right?"

"—Would you like to try?"
