In Buddhism, Virochana is the greatest of the "Dhyanibuddhas", the Five Great Buddhas of Wisdom. He encompasses the principle of "Absolute". In Tibet, he is said to ride a snow leopard as his mount. He is also said to have introduced the Yogacara school of Mahayana Buddhism to humans. He is called Dainichi Nyorai in Japan. His wrathful emanation is called Acala (or Fudo Myo-O).
In Hinduism, Vairocana is the name of the king of Asuras who, together with Indra, went to Prajapati for guidance towards enlightenment.
Known as Virocana, his material card, 1000 Lotus Petals, can be acquired after the Virocana demon is defeated in the 7th area of the Bomb Shelter, located inside Kasugayama High School.
In Tatsuya's Scenario Virocana resides in the Tower of Reason in Kadath Mandala. He questions what the true essence of the self is, atman? Is there or is there not an "I" on the inside. Maya's answer of saying there is a "I" angers Virocana who wishes for the woman of Illusions who unmasks the truth to disappear from his sight.
After visiting the Satomi Tadashi drugstore inside Kadath Mandala, Virocana reappears. Proclaiming that the self reflected in the water is the true self atman and the truth of the universe, Brahman. As ones pursuing the truth he grants them wisdom and the Trapezohedron of Reason.
