Teacher System

The Teacher System or Mentoring System (師範システム shihan shisutemu) in the Elder Tale allows high-level players to temporarily lower their level and stats in order to play with and guide new players.

Shiroe used this system to train Minori and Touya prior to the Catastrophe.

The purpose of lowering the teacher's stats and level was to allow the monsters to focus on the student players, as monsters would become attracted to the highest-level party member; the Hamelin hunting party tended to fail because of Shredder's failure to use this system, thus always attracting all the monsters and the lower-leveled players' formation would never work.

Roe2 also uses this system after meeting Touya's Party; because of it, she was only capable of summoning one Pale Horse at a time.
