Something that out of curiosity regarding Issei and Vali's Diabolos Dragon:

In Issei's case; looking at the chant, does he always need Ophis to be by his side whenever he activates Diabolos Dragon?

In Vali's case; Since Ophis only chanted one line for the first activation, and once Ophis is no longer needed to help Vali activating his Diabolos Dragon - will the chanting remained the same, only without Ophis' line, or the chant will be modified again?
