In the tenth episode of "A Scientific Super Electromagnetic Cannon T", the old thief of Kihara can be described as out of the limelight. Misaka Mikoto and Bee Eater, two of Gakuen City's rank five, were toyed with between their legs. Kihara's idea is very clear, that is, to control the Misaka network, from the moment Misaka Mikoto and bee eating qi action, they have fallen into the trap of Kihara Fantasy.

At the end of the last episode, the bee eater prayed that he had been deceived and hurriedly drove back to the base. Why is the bee eater so nervous? Mainly in this episode, an important device [external substitution brain] is mentioned, which is the DNA computer of the urban legend that Satan Tears and Hatsuharu are looking for. [Outer Substitute Brain] is a very dangerous and powerful device, bee eater and Misaka Mikoto used this device when driving back but were blocked by traffic.
Simply put, the device is an amplifier of the bee-eating prayer ability, which can allow the bee-eating prayer to manipulate thousands of people within a few kilometers. But in fact, the birth of the "Outer Substitute Brain" has other uses, which are somewhat similar to the sister's plan, which are the dark side of the Gakuen City, and they can't see the light. His real role is to enable ordinary people to simply log in and also have the ability to manipulate minds.
There are also similarities between the production of the Outer Brain and the Sister Plan, which uses the flesh and blood of the Level Five Abilities. [External Substitute Brain] is a super brain cultivated by the cerebral cortex of the bee-eating exercise. The real purpose of the bee eater's discovery of this device was when he made friends with Dolly, Misaka's first clone. Dolly's death had a great impact on the bee-eating exercise, and then he used his ability to manipulate the people involved in this experiment to learn the true purpose of the "External Brain". However, the bee-eating prayer did not destroy the device, but brainwashed the relevant personnel and appropriated the device for themselves.
This device has long been developed and matured, and it also has the ability to allow ordinary people to have psychological manipulation. This is why after the old thief of Kihara stole the house, the bee eater panicked. Although the bee eater prays for someone else to log in to the "Outer Substitute Brain" is cumbersome. However, the old thief of Kihara skipped the login part, directly let the [external substitute brain] synchronize with his own brain waves, and directly encroached on the [external substitute brain] device.
The purpose of the Old Thief of Kihara is simple, or to activate the Misaka Network to create a level six ability that can reach the realm of the gods. However, this time, the person he chose was no longer a party pass, but chose Misaka Mikoto. After the old thief Kihara injected a virus into the Misaka network with the "External Substitute Brain" and manipulated the Misaka network. Misaka Mikoto came and fell into the trap, and the black lightning gathered in the sky fell on Misaka Mikoto, will Misaka Mikoto become a god? The old thief of Kihara is very abominable in this episode, who can save Misaka Mikoto?
