Full Summary
"Magic and Science. Should I destroy everything in this world that has cut me off?"

'''Aleister VS the Church of England. Where does this lead to?'''

Aleister, who left behind his stronghold Academy City without hesitation, started a general offensive on the magical metropolis of England. In this seemingly unjust operation, for some reason, Kamijou, Index, Accelerator, Hamazura and Takitsubo can be seen...

The seal that was used against the great demon Coronzon, whose power surpasses that of the great angel Aiwass, is soon about to be unraveled. Before this could happen, they must obtain the demon's weakness within London, but since Lola, who is being possessed by Coronzon, leads the Church of England, it is inevitable that this would be seen as an invasion from the Science Side.

Kamijou threw the gauntlet on a decisive battle desired by no one. Beneath this fierce situation, the one who saved him from this predicament is the certainly gentle manager-type airhead onee-san, Orsola???
