1After sharing her family history with Hachiman and Yui, Yukino asks for one final request: to watch her as she works to exceed her parents' expectations. Not long after, Isshiki Iroha visits the trio looking to jazz up the annual celebration for the graduating seniors...by throwing a Western-style prom! Yukino sees this as a chance to prove herself and agrees to help, but there's a catch--she wants to do it alone rather than as part of the Service Club! While few can doubt Yukino's capabilities, is she in over her head...? The final arc of this off-kilter youth romantic comedy begins!
