The seemingly endless Sakura series reaches its thrilling conclusion! Sakura, having heard tales of a holy grail in Ulbuka, successfully makes a voyage to the western continent only to be besieged by crabs and Qiqirns on all sides! How will she ever work her way out of this one? Pioneers who read it report having their monster rearing rank increase by one.
The "Sakura and the X" line of key items may be a reference to the Japanese animated television series Cardcaptor Sakura, which used the same format for naming episodes. This might be coincidental, however.
Additionally, the holy grail is an artifact in the legends of King Arthur.
