In episode 4 of Chuunibyou demo koi ga shitai, when Mori Summer was fighting Mjolnir Hammer for the possession of Mabinogion, Mori Summer used the incantation,
Reality, be rent! （はぜろレアル！） Synapse, break! （はじけろシナプス！） Vanishment, this world! （バニシュメントティスワルド！）
This is the same incantation as what Tyrant Eye uses to transform (henshin). Mjolnir Hammer and Dark Flame Master also uses the same incantation. If I remember correctly, Sophia Ring SP Saturn VII also uses the same incantation. This is understandable since Sophia Ring SP Saturn VII was friends with Dark Flame Master and went to the same school if I remember correctly. Tyrant Eye came into existence due to Dark Flame Master. Mjolnir Hammer is servant to Tyrant Eye. So them sharing the same incantation is perfectly understandable.
However, Mori Summer who went to a different school and has no connection whatsoever with them, except Mjolnir Hammer, was using the same incantation. Why is that? Is there an in universe explanation why Mori Summer is using the same henshin incantation despite coming from a different branch of chuunibyou-ism?
