Tooru is just obnoxious loud liability that Aoba Jobsai who they always Tunned out to even when he is serious about to talk about zombies. oikawa just spamming zombies nonstop for weeks when the birds are gone and the air taste like blood and metalic, but no one cares as they don't even listen to him as he is an obnoxious loud liability who does not even know what he is doing anyway as he does not have y/n's notes on how to survive, y/n know how to survive while he doesn’t.
