It wasn't until the school principal mentioned "rigorous medical examinations and various intelligence show that [Realm of Innocence] this game does not cause any physical or mental burdens to the players, and twelve hours of daily gaming can fully counterbalance eight hours of deep sleep under normal circumstances", that I finally understood.
The ambitious senior management of the schools and the parents, who seek to fill their own youthful folly and regret with their subsequent generation, seem ready to further 'up the ante' for their children.
The conclusion did not surprise me. The principal and the parent representatives skillfully expressed a plan which in my eyes could clearly be called 'despicable', under the pretenses of 'more efficient learning', 'a more relaxed environment', and 'making the most of time'.
They hoped to establish a special 'tutoring class' for the children to continue their study in the game every night.
