The story has some elements which contradict the current canon(like Aizen's friendship with Urahara, Isshin and others; it's apparently written before Turn Back the Pendulum) but otherwise, an excellent one-shot. It humanizes Aizen somewhat and is a sentimental story about old friends gathering for a drink and realizing that one person is missing.
