—Noboru Mochizuki to Haruko Mochizuki, Thus Spoke Kishibe Rohan - Episode 4: The Harvest Moon

The Mochizuki Family (望月家 Mochizuki Ke) is a family both introduced in and acted as the main group of focus within the one-shot, Thus Spoke Kishibe Rohan - Episode 4: The Harvest Moon, as the current family must deal with a mysterious curse that has been affecting their family lineage for decades.


Current family

The Mochizuki family currently consists of five family members and their pet dog.[1] The complete family genealogy goes back sixteen generations, with the family being around as far back as during the time of the Battle of Sekigahara.[2] The current family resides in Morioh, as Rohan Kishibe states they live near him.[1] Their real family name is unknown since Rohan used "Mochizuki"[Note 1] as a pseudonym before telling the story about them.[1] Every direct descendant of the family shares the exact date of death[3] of September 8th, the date of the Harvest Moon[4], which ties to a curse that has been dealt with for every generation.

Family Curse

I suppose I'll return to the skies... Though I come back every year. Time will always continue to flow... Generations will come and go... and within this family, someone will eventually get careless, and forget the rule to always go moon viewing during the Harvest Moon.

Every year during the Harvest Moon, they must view the moon altogether until midnight.[5] If they follow this rule, they will live long lives, as shown by Seizo Mochizuki and his wife Sae, both living to 100+ in good health.[6] However, if a family member doesn't follow the rule, they will be killed by unfortunate events. These unfortunate events can be seen with Noboru's brother Mamoru who died by drowning at 17 while trying to help a neighbor's kid from drowning, and his father Sakuzo, who died of an allergic reaction to a giant hornet sting at 46.[3] Unbeknownst to them, the family is stalked by a spirit known as the Moon Rabbit, who is the one that brings misfortune to anyone in the family who doesn't follow the rule. The origin and reason why this curse has befallen this family for past, present, and future generations to come are unknown.

One way to avoid this misfortune is if a family member accepts someone's hand in marriage. This condition is met when Aki is narrowly spared of misfortune by hornets by accepting her boyfriend's proposal, thus causing the spirit to proclaim she is no longer part of the family in mind or body.[7] Instead, the misfortune was redirected to a motorcyclist driving by that caused them to crash and be killed to even the balance.[8]
