The robot (大) and the Queen of Hearts (qi) reached an agreement in the space station's bathroom (Ø4). Lacking a proper pen they sign their written deed (契) with an engraver (㓞).
Maud Younger used to wear a monk's cowl when leaving the space station, but when she got a royal ermine coat she gladly threw the monk's cowl out. Nowadays she uses to wave a petal leaf matching her new coat.
