Spoiler for The scene between Klan and Alto:
Alto :"Why did you join the SMS Klan?"
Klan:" "This is a tradition for us......."
She thinks about Michel....
Alto :"I thought that too... That I would become an actor.But I loved the sky and wanted to be a pilot...."
Alto thinks about Ranka
Alto:"And... I met her.I choose to join SMS to protect her. Fighting, protecting and forever after that..." (to be with her forever ?
)
Klan:"All of a sudden speaking about the past..."
Alto: "It's true... that maybe I had been running up to now. Pretending I didn't notice a lot of things." (huh guess about who he is talking here....)
Alto:"But. That too will end. This world can be detroyed at any time... But everyone's living here. They want to continue living here. That's why... If Ranka is going to be made into a tool by the Vajra. If her songs are going to be used to destroy us. I will (he takes a deep breath) kill Ranka."
Klan:"Alto... that is your love? "(she is talking about Ranka it's obvious... )
Sheryl:"I knew it all along. But just for now... just a little longer..."
Yes, no one could misunderstood the context of which the word love was said...
He loves her .. I think it's obvious now...
