As usual, the picture and original Japanese text were done by  lycanthrope-bata, while I did the translation from Japanese to English, I hope you enjoy.^^

Oratorio, Apnitos and Von are going to school together.
The other two being Bioroids, Von is actually the oldest of them.
Yet, Oratorio and Apnitos are attending a general teran school by the Emperor's will.
Both Oratorio and Apnitos head from the court to Von's home in the Gakuentoshi district each morning and then all walk together to school on foot.
Oratorio is akin to the son of Curl, while Apnitos is similarly related to Litola.
They both study together with Von and act as both his friends and his bodyguards.

...seems though, they'd better act as the kind of person who let poor Von copy their physics homework today.^.~
