The initial persona of Naruaki Seta and the alternate of Yu Narukami. There's not much else to say except that he shares Yu's voice. You're free to do an impression of either the English side or the Japanese side. Extra voice effects are allowed, too.

There will be more than just Seeker for this voice... [Wink.]

The Awakening Phrase is the only portion of lines that have that "Persona Speak". The tone of formality and power, y'know? It is only with the last two audition lines that I want to hear more Yu than Persona Speak. When I want the personas talking beyond the Awakening Phrase, I want to hear more of their canon selves; their personalities and their normal tone of voice.
