No actual process and off-screen, Lara is being astral projected into adult to go on a date with her teacher I believe, she's like a spirit while in this form.

The AP was teased at the end of the fifth volume and the scans for the sixth took years to appear, the quality of the scans of this last is terrible.

I believe this is Rururu's last work to date. Attached bits from another chapter as well.
