Apparently you can miss these if you don’t use the character fast enough. By the time Akihiko was available I had already hit the border floor and I didn’t get to see his.
That’s about what happened for me with Aigis and Koromaru, I was pretty consistently just using Aki/Mitsuru/Yukari and didn’t get to see their intros At least I got to see Ken’s when I replaced Aki with him though
Because most of P3 characters already got Persona or awakened behind the scenes. Only exeptions is MC nad Fuuka which, both got awakening cutscene. That would be very strange to show cutscene of summoning of Mitsuru's Persona, considering that she have it for about 10 years
Tf are they supposed to do? Have a mental breakdown? All they're doing is figuratively killing themselves and steeling their resolve. It wouldn't have the same introspective breakdown the P5 crew needed to summon their own since they are figuratively building up the courage to kill their normal selves to reveal their true self
