Sneaking In

Gustav made calculations as he prepared to leap, "I guess it's time I finally made use of it..."

The building was only about three hundred feet ahead, but Gustav had decided to leap over it.

As he stood properly, he leaped forward with speed. His body travelled upwards and forward in an arc-like trajectory as Gustav stared at the multiple buildings below him, turning smaller.

As his body arrived hundreds of feet above the last building, he descended towards its back.

It was at this point that Gustav brought out an invisibility button and made use of it.

Zwish~

His body disappeared into thin air in mid-air. Now, not only his presence couldn't be sensed, but his visibility too was gone.

As Gustav's body descended towards the back, he spotted the window he was aiming for, which was slanted diagonally.
