Anime Like Senjuushi: Kijuushi-tachi no Happy Birthday!
SYNOPSIS
A group of noble musketeers decides to throw a surprise birthday celebration for their beloved Master. Set after the main story's sixth episode, this one-shot OVA shifts focus from grand battles and noble intrigue to something far more intimate: watching these warriors juggle the chaos of party planning while staying under wraps. What unfolds is a collision between military discipline and domestic comedy. These seasoned fighters must coordinate decorations, gather supplies, and keep a secret, all while maintaining their usual routines around someone they're actively trying to deceive. The tension between their serious nature and the ridiculous situations birthday prep creates drives the humor throughout. The result lands somewhere between heartfelt and absurd. You get genuine glimpses of how much these characters value their Master, but the path to expressing that affection is paved with mishaps, close calls, and the particular strain of trying to act normal when you're obviously hiding something. It's a breather episode that lets you see these soldiers as people who care deeply, even when they're bungling the simplest tasks.
