So I picked the sacrifice Ejika side of the story and it felt actually worthwhile to do so i was getting annoyed with Ejika through both Anemos and Pagos and just sighed when he turned during Pyros but Hydatos actually surprised me with how the story was and left me wondering why couldn't the other 3 installments have been as engaging as this one. It was nice to see someone using their head a lot more to tackle a foe they couldn't hope to stop alone but it left me pondering how did Ejika resist the primal Eureka's influence while wielding a weapon with its essence much like they pointed out it was similar to Zanzetsuken. The conclusion that i got felt heartfelt and made me feel like Krile might grow as a person
Then i went and cleared BA and got to see the true end to Eureka so Krile learns how to bring people back from the lifestream from Kan-E-Senna so i'm glad that is teachable and not a Padjal exclusive ability may mean more shenanigins with lifestream hopping with flow etc in the future who knows, she learns this because she theorized that Ejika might still be brought back when all of the primal Eureka's weapon aether was gone this works ofc and we learn that Ejika thought it was a possibility but resigned himself to Death. And while i can appreciate the character growth of Ejika I feel this was at the cost of Krile's character growth rather than trying to move on and see why people around her did what they did leaving her behind they have her get the complete happy ending here of my friend is back he'll look after Euerka/Isle of Val and she can go back to the Scions. Suffice it to say from the Ejika sacrifice route this feels worse than the base ending of Hydatos.
Also how do people feel that story segments are hidden behind something like BA?
This is all from me seeing the Ejika sacrifice route so if anyone can tell me how the other route is like be very interested to hear it
