Shogunyan is a dull, blue cat with a white face and big, black eyes. He has a tiny, dull, pink nose and gold inner-ear coloring. The tips of his paws are white. He wears a turquoise samurai hat on his head with a big, gold crescent moon on the centereand accenting of gold and a matching samurai armoru suit, an orange sphere attached to a collar, and an orange rope that holds his sword. His tail flames are gold.
Unlike Jibanyan, Shogunyan is dignified but also a bit rash. He speaks in old dialect and ends his sentences with "de gozaru" in the Japanese version. Shogunyan takes his status as a samurai very seriously and hates it when others disrespect him. As seen in the anime, he got furious at Nate and Whisper for not sharing the cake he sliced up and attacked them. When he was young, he practiced his skills by slicing up katsuobushi. Since he couldn't find any in the present, he went berserk and sliced people's things.
Before disappearing or wandering off, Shogunyan bursts into tears after witnessing Nate and Whisper´s friendship and asks them to take care of his descendant Jibanyan.
In the anime, Whisper reveals that Shogunyan is one of Jibanyan's ancestor spirits.
Shogunyan says that he is looking for his ultimate rival. It is turned out that rival is actually Komashura.
Shogunyan is a spectacular sword fighter and, according to the Yo-kai Medallium bio in Yo-kai Watch 2, his "sword [is] so sharp it can even slice [his] description in two!"
As a Legendary Yo-kai, one must befriend/recruit the following Yo-kai first in order to undo his seal.
First debuting in The Legend of Shogunyan, where Shogunyan was summoned when one of Nate's Medallium Seal Pages glowed and the seal on him was broken by his collected medals. Originally appearing as Jibanyan when summoned, he enters the closet (disturbing Hidabat while doing so) and then emerges as the legendary Yo-kai, though he is still believed to be Jibanyan in a disguise upon emerging. Immediately, he shows his ancestral tie to Jibanyan by taking a selfie of himself and reading his descendant's magazines. Following a showcase of his swordsmanship to Nate and Whisper, he is later offended when they do not offer him any of the cake he previously cut in thirds and attacks. Though he comically cuts Whisper in half, Nate's display of worry over his friend's safety touches him and he gives Nate his Medal. He then enters the closet again, bidding them farewell before Jibanyan emerges once again.
He is first summoned in Yo-kai Baku just to give Baku a legendary dream so that Nate's classmates will wake up.
In Shogunyan Wants to Cut Hard Things, he goes on a rampage and slices things due to the fact there were no more of the stuff he likes to slice. Although he did help Buchinyan split back into Jibanyan and Whisper, Whisper ends up crashing into Shogunyan and they become Whisshogun, thus shocking Nate. It is unknown how Shogunyan and Whisper split apart because the episode soon ended.
In Yo-kai Gojidatsujii, Shogunyan, along with other cats Yo-kai, were summoned all together due to Misterr Typoo's power changed the Robonyan F's Dream medal's name to 'Nyan'. Unfortunately, shortly after Misterr Typoo running away for his life, Nate accidentally said that he summoned all of them for nothing, thus unintentionally upsets the cat Yo-kai and this led to them proceed to beat up Nate and Whisper as the episode ends. During this end scene, Shogunyan is one of those Yo-kai who didn't weld a shinai (a type of bamboo-made katana made for practicing kendo.) while beating up Nate and Whisper and in his case, he is seen wielding his sword instead.
Shogunyan appears as a supporting Yo-kai during Episode 2: Jibanyan's Brilliant Strategy, alongside Jibanyan and Robonyan F.
One scene involves Jibanyan as Jetnyan, alongside Robonyan F's help, to push a heavy cart Amy was trying to push, with Shogunyan offering help in spirit, though Jetnyan put too much power into the thrusters, causing the cart to fly through the aisles. Shogunyan helped to clear a blockage on the path Jetnyan and Robonyan F were guiding Amy through.
