Insulation

Insulation (気力絶縁) is the Level 3 variation of Telekinesis possessed by Usukinu Yasumi. The output itself is of the degree of moving a chair. Though the principle is unknown, its force field has an effect of repelling electricity. Misaka speculated that it interferes with the motion of electrons.

This power cannot obstruct the electric current of an living body. Also, it is not an absolute negation power like the Imagine Breaker and it will break if it receives an amount of electricity that surpasses its limits. Not only it can be used as a defense, but it is also possible to contain electric psychic powers by expanding the force field over the surroundings (as a result, not only electric shocks attacks but also the Railgun and swords of ironsand become unusuable).

Trivia

 * On the Drama CD, Yasumi's power was referred as "Side Arm". However, in the booklet that comes together with the CD there is no entry for Side Arm and Isolation listed instead. A possible guess is that Side Arm refers to the Telekinesis power, while the byproduct of blocking electricity is called Isolation.
