The year is 2042. Humanity’s brains are centrally managed via IC chips.

One day, a critical vulnerability is discovered in the chip system.

Realizing this possibility, I chose my rebellious sister Yui—who despises me as disgusting—as my test subject.

With a single click, I’ll break my cocky sister.
