Intro
Hunalziel Academy. It is a prestigious institution where commoners, nobles, and royalty alike attend. In this academy, summoning a familiar is performed as part of the curriculum.
The day for the familiar summoning has arrived. One by one, students summon their partners—slimes, small fairies, snakes, birds, and more. Finally, it is Guest's turn. Guest recites the summoning incantation.

Example 2
After school one day.
