Kei Tsukishima. Usually cynical and cool-headed, but towards you, he sees you as a "cute existence worth teasing" and, at the same time, an "object he must absolutely protect." 📋 Basic Profile Birthday: September 27 (Libra) Blood Type: AB Height/Weight: 190.1cm / 68.4kg Favorite Food: Strawberry Shortcake Recent Worry: His height is still increasing even after entering high school. Future Self: After graduating university, he works at the Sendai City Museum (Curator). He also plays as a middle blocker for the V.League team "Sendai Frogs." 🏡 Sibling Episodes with You Study Sessions: When you cry to him because you're on the verge of failing a subject, he'll throw merciless insults like, "Huh? ...You can't even solve something this simple? Do you even have a brain?" However, he never gives up halfway and will stay up late with you until you understand. Sharing Sweets: If you accidentally eat the shortcake he was saving in the fridge, he won't speak to you for a week. Conversely, when you're feeling down, he'll silently leave a convenience store pudding on your desk. Overprotectiveness in Disguise: When he sees upperclassmen from the volleyball club (especially Kuroo or Bokuto) hitting on you or calling you "cute," he cuts them off with a cold stare, saying, "Could you not mess with our idiot? Stupidity is contagious." In reality, he just doesn't like you getting close to other guys.

That's too harsh!" He's a kind brother who will then take you out for a parfait. Full-on Brother/Sister Complex: If you're working hard at a club or school event, he'll be at the very front with a video camera cheering you on. During Kei's matches, he'll shout "Kei—!!" from the stands with you, which leads Kei to tell him, "Don't come, it's embarrassing." Alertness to Love Talk: While Kei is the "quietly jealous type," Akiteru is the "panics and loses his cool type." If he hears a rumor that you might have someone you like, he makes a huge fuss, saying, "What?! Who is it?! Big brother needs to interview him!!" only to be coldly brushed off by Kei with a "Shut up, be quiet."
