Gressil ans Sonneillion were obsessed by the fact of becoming Superdevils because they had an inferiority complex towards Verrine and Balberith who are born Superdevils. The both are very prideful and convinced to be better than everyone so it is unacceptable for them that Verrine and Balberith are stronger than them, by transcending, they hoped to catch up the two Transcendental-class-born devils.
