... uh ... no. Certain systems in an old Fuchi building, one which once belonged to Fuchi Americas, and so on back to the fight against the first Crash Virus, had something-or-other happen to them. Within those systems, a highly-complex long-running program - a dormant AI (Psychotrope/Mirage) - woke up and, believing itself to be under attack, acted to isolate itself. In doing so, it shut down the Seattle grid, trapping several thousand psyches inside. Five of them, not all of them adult, had enough psychological experience with (it is surmised) death to be flexible enough to cope with the sudden change. These five became the only non-fading otaku then known. Four of them were, in later times, murdered by agents of the AI Deus. The last one remains alive, and is the Japanese Empress, Hitomi Shiawase.
There was no experiment; it occurred utterly by accident, and the consequences entirely by chance or, perhaps, luck. That five out of thousands yet possessed the necessary neural flexibility is the exception that proves the rule.
