Considering that the Western title for Eva is Neon Genesis Evangelion, I don't think there are any specific naming criteria beyond what Digi feels like discussing or, in this case, what he thinks will do well with the algorithm.
Still, a part of me is morbidly curious about what he'd have to say about Eureka 7. I bet he'd skirt around the entire part about growing up into a man and he'd hyperfocus on Eureka and Anemone instead: mostly because he naturally gravitates towards talking about the rainbow-coloured anime girls, but also because he'd probably try to draw a forced parallel between his transition and Eureka's metamorphosis at the end of the show.
I didn't wanna weeb out but seeing it's a show about growing up, hiding under an action veneer. Just lemme ramble for a bit.
The show is mostly about accepting people other than yourself, letting go of past demon and growing up. We see the growing up through the main male characters and how all get changed through their relationship with their female partner, who change too.
Renton goes from a clueless bumbling child idolizing larger than life situations, only to later come to terms with how much he didn't know and didn't want to accept. He goes from having a crush to making the main girl (who he cringed the fuck out before) his wife. This is Shinji from NGE but if everything worked out in the end.
Dominic the military investigator gets tied to the hip with a female super soldier that he treats like a tool (she is quite impossible to handle), drugging her up and telling her to get to battle (get in the mech bitch), only to later realize that the military is doing way more fucked up shit; mans up afterwards.
Holland is the leader of an infamous gang of skysurfers idolized by Renton who's group in reality is a group of anti-state terrorists. In his time in the military he was dating Renton's late sisters who's shadow and fallout after leaving the military causes him to lash out against his crew, his current lover and to avoid responsibility. His character is what made my entire rewatch worth it.
This entire show is about growing up, manning up and carving the best path. When I watched the show as a teen I was only interested to see where the main ship went, on re-watch Holland and the other characters made the show for me.
I think Digi is still afraid of rewatching it. I remember his saying back in the day he still didn't rewatch it because he didn't wanna re-evaluate it for fear of not liking it as much as the first time.
