Hakuho warned, Kisenosato gets master's degree, two stables close

The Yokozuna Council meets to discuss Hakuho and retiring Kakuryu. Kisenosato impresses with his graduation thesis. Tournament info for May and July is announced. Azumazeki and Minezaki stables reach the end of the road. We have the latest on Kotokantetsu (who quit due to virus fears) and Hibikiryu (injured terribly last week). And two prominent sumo figures pass away.
