Muv-Luv Alternative

Visual novel where Takeru Shirogane loops back to the start of a war he's already lived through. He wakes in his room three years after previous events, realizes he's been sent back in time, and gets a second chance to change humanity's fate. The story centers on his attempt to help complete a project called Alternative IV—an alternative to a grim existing plan—while navigating relationships and military conflict. Expect heavy focus on character bonds tested by impossible choices, war scenarios that escalate throughout, and a narrative that assumes you've played the prior Muv-Luv entries. It's structured as the concluding route of a trilogy, not a standalone entry.
