WonderCon 2016

For high school student Aoba Watase, his boring days end when a bright light suddenly appears in the sky above and a giant mech attacks the city. As this mech chases him, he's saved by pretty female classmate Hina Yumihara, who has her own mech and came from the future to protect him from assassination. When they're thrust into the future, she gives him a cryptic message before disappearing and promises that they will someday see each other again, as she has feelings for him. After arriving in the future, Aoba sees battle mechs in combat in the sky above him.
