Code Geass: Haruka of the Confrontation

Two months have passed since the Sunshine Insurrection has ended after the Sacred μ's Empire was dismantled, but it seems like true peace was far from being achieved. An organization calling itself the "Association of Girls Band", shortened to A.G.B., had initiated the Second Great Knightmare Acquisition Rush with the intent of launching attacks against school idols in order to exact their revenge for all the mistreatment they suffered under the Sacred μ's Empire's regime.

Haruka Konoe, the leader of the School Idol Knights as the Knight of Shinonome and Yohane Zero's most loyal knight, now has a Geass with an ability to detect enemies from a wide range. With it, alongside Zero's skills as a leader, they shall lead the School Idol Knights and the Sunshine Black Knights respectively in order to gain victory against the A.G.B. in the upcoming conflict against them.

Unbeknownst to them, their main Knightmare Frame provider, the Tsurumaki conglomerate, had a secret allegiance to their enemy faction.
