Like Keith is Danny, and Shiro is his protective older brother. Keith lives with Shiro and Shiro’s girlfriend, Allura, who (along with Coran) are super into the supernatural and ghosts (particularly hunting them).
Keith’s friends are Pidge and Hunk. They were there when Keith had his accident, and they both help him out whenever ghosts (who come through a wormhole Allura accidentally created when Keith caused the accident and call themselves Galra) attack the school.
And like, the best part? Keith has an incredibly huge crush on Lance, who also happens to secretly be a super skilled Ghost hunter hellbent on capturing Keith and sending him back to the Ghost zone. They’re like sickly in love, but have no idea that they’re secretly arch-rivals who fight every week. ((They do that baby project together, and thats actually how they start dating despite getting a D on the project)).
Lance has no idea that Sendak (Vlad) is also a ghost, and let’s just say when he finds out, he is hella pissed at Sendak, and eventually joins Keith in helping to fight the Galra.
