Zenless Zone Zero: Ellen? She's My Student

I don’t want to fight readers over their wives, so this book has no heroines. Synopsis One: 2,500 years ago, the King of Qin unified Blue Star. From then on, the entire planet had only one country: Qinlong. With no enemies, the leaders decided to focus on development, hoping to explore distant alien civilizations. They wasted enormous resources on it, but all their efforts came to nothing. Overexploitation left Blue Star with little time remaining. Its resources began to collapse, and the land could no longer be farmed. At this desperate moment, a force calling itself the Universal Federation arrived from space. They brought Blue Star a glimmer of hope. They would randomly select one person from Blue Star as a savior and send them to another disaster-stricken planet. If that person could help the planet overcome its disasters, then the calamities on Blue Star could be resolved as well. But if that person died, Blue Star would face a devastating punishment. The destination was a planet plagued by Hollow disasters. There had been ten chances in total. Nine had already been wasted. For the final attempt, Long Tian, a dragon demon god reincarnated from Teyvat, was chosen as the savior. Can he overcome the Hollow disasters and save Blue Star? Synopsis Two: Ellen: Teacher Long is really responsible and treats his students well. Of course, I wouldn’t mind if he gave me a little less homework. Billy: Long Tian is a good buddy of mine. His stories about Armor Heroes are my second favorite. My favorite is, of course, the Starlight Knight. Wise/Belle: He’s an exceptionally capable Proxy.
