Ominaeshi no Kage

--Go and observe the world--.

So charged by her clan,
the protagonist departed for a certain school.

The clan's elder was old friends with the principal.
It was a place where ninjas train.
The protagonist joined the Sixth Year program
to support those students in field practice.

She would be here for one week.

So charged and so fulfilling her charge,
she settled into quarters for that week, living among
six distinctly individual students in the sixth grade.

It seemed simple enough.
But there was a hidden meaning to her mission---.
