==Role==
===Fate/Grand Order===
==== Subspecies Singularity III: Shimosa ====
Amakusa Shirou traveled across many worlds for twenty years until Satan called to him. Much like him, their brethren were slaughtered as well. They grant him a portion of its power to perform a ritual to achieve his goal of mankind's destruction in revenge against the Tokugawa. They direct him to Shimosa,Fate/Grand Order - Shimosa Province: The Stage of Rivers of Blood and Mountains of Corpses, Section 14: The Stage of Carnage, Onriedo (Middle) where he meets Ashiya Douman. He also met Sasaki Kojirou there in the Hitachi mountains, and takes him as bodyguard.Fate/Grand Order - Shimosa Province: The Stage of Rivers of Blood and Mountains of Corpses, Section 5: Inferno (Middle)
At Katori Shrine, he summoned Tomoe Gozen, Minamoto-no-Raikou, Shuten-douji, Mochizuki Chiyome, and Houzouin Inshun with the Holy Grail. Douman then infused them with the Curse of Annihilation to turn them into Heroic Spirit Swordmasters with unintended expection of Inshun.Fate/Grand Order - Shimosa Province: The Stage of Rivers of Blood and Mountains of Corpses, Section 2: Purgatorio (Middle) Yagyuu Munenori joins them despite being human for a chance to duel Miyamoto Musashi again. 
They are instructed by Amakusa Shirou to kill everyone in Shimosa. Both their souls and the grieving souls of those they slaughter will serve as the foundation of Onriedo Castle. Once it is constructed, Amakusa Shirou will sacrifice one of Tokugawa blood to it. The sacrifice will serve as the perfect catalyst to cast a far-ranging multilayered curse on the Tokugawa regime. This will destroy any possible world where the Tokugawa exists.
Later, Amakusa Shirou and Douman both note they're missing Inshun as the Swordmasters must number seven. Douman then turns day into the blood moon night on Amakusa Shirou's instruction.
Douman later reports that Inshun is gone, blaming it on his incomplete summoning. However, he is pleased that he fulfilled his role as a Swordmaster. Munenori disagrees, considering Inshun a failure for failing to take even a hundred lives. Despite that though, Amakusa Shirou says Inshun still served as an excellent cornerstone for the Onriedo. Douma agrees with him and Munenori, saying the souls of Heroic Spirits are insufficient to manifest the Onriedo. Thus, the grieving souls slaughtered by the Swordmasters are also needed. Sasaski suddenly enters, so Amakusa Shirou explains why a mere human is amongst them. He then leaves, commanding the Swordmasters to continue killing while he prepares for the Onriedo’s arrival.
He later orders Chiyome to deliver a letter to Toke Castle threatening to assassinate Kiyohime. Chiyome reports her success, expecting security around Kiyohime has increased by now, and rumors should be already circulating around town. Amakusa Shirou orders her to assassinate Kiyohime after letting panic about her assassination to spread throughout the population. Afterwards, the populace will be instilled utterly with fear, thus their souls will be better sacrifices. Amakusa Shirou then departs, telling Chiyome that she only needs to stay true to the serpent within.Fate/Grand Order - Shimosa Province: The Stage of Rivers of Blood and Mountains of Corpses, Section 7: Paraiso (Beginning)
After Chiyome’s second attack on the castle, Amakusa Shirou commends her for killing forty-odd samurai stationed there. While that is not many, their deaths will terrorize the populace. With her role fulfilled, he declares she will be removed now. He then orders Shuten to connect Chiyome’s heart and brain to the power of Yamata-no-Orochi in herself, needing Ritsuka and Musashi eliminated.Fate/Grand Order - Shimosa Province: The Stage of Rivers of Blood and Mountains of Corpses, Section 9: Paraiso (Ending)
Following the demise of Shuten and Raikou, Amakusa Shirou prepares to materialize the Onriedo. On his order, Douman turns day into the blood moon night. Amakusa Shirou then uses the souls of five Swordmasters and their victims to transform Toke Castle into Onriedo Castle. He mocks the dead Sakon for having been horrified at the carnage unfolding, recounting how Sakon killed thousands of his comrades including women, elderly, and children without hesitation, and slaughtered Christians under the insistence they weren’t human. He delights that now marks the fall of the Tokugawa, believing Satan will be pleased. Despising this world for accepting the Tokugawa and forgetting Shimabara, Amakusa Shirou vows to avenge the atrocities of Shimabara through Onriedo Castle.
Inside the castle, he has Kiyohime restrained, intending to sacrifice her as a catalyst to activate Onrideo Castle due to her Tokugawa hertiage. He declares Onrideo Castle will destroy Chaldea after it destroys Shimosa. He confirms to a confused Kiyohime that he lost his sanity ever since Shimabara. However, if he is insane, then her family is hateful, cruel, and inhuman because in every world he visited they repeated their massacre of Christians. For that he will kill the Tokugawa despite knowing this Shimosa is cut off from the proper history. He then tells Sasaki that Musashi is in the castle. He declares he will kill her, believing it is the sole reason for his existence. She has yet to reach the pinnacle of her swordsmanship, while Sasaki already reached his. Sasaki is concerned he may not get the chance to duel her since she will be facing Munenori first. Amakusa Shirou replies nothing is certain except the destruction of this world by Onrideo Castle.
He prepares to sacrifice Kiyohime when Senji Muramasa and Fuuma Kotarou arrive and rescue her. Hearing that Kotarou knows his Heroic Spirit counterpart, Amakusa Shirou declares he and his counterpart are nothing alike if his counterpart would stand with humanity. Amused that Muramasa realized his role is to stop him, he confirms the Counter Force reaches this far. He would’ve left him alone if he remained at his hermitage, calling him a fool for confronting him now. He then declares Muramasa can’t do anything to him, for his body is now equal to a Swordmaster. Kotarou and Muramasa attack him, but their attacks are useless. Amakusa Shirou is disappointed in Muramasa, having thought he’d have the means to defeat him since the Counter Force summoned him. However, his confidence in his assured victory is disrupted by Ritsuka and Musashi. He deduces this means Munenori is dead, saying he wouldn’t have lost if he fully embraced Satan. He insults him, but Musashi defends Munenori’s pride as a swordsman. She accuses Amakusa Shirou of being envious, saying he should’ve killed people rather than turning them into monsters if he truly hated the world. Amakusa Shirou calls her no longer human because she travelled across many worlds like himself. He calls her an unwanted outsider rejected by every world she visits, never able to return to her own world that was now gone. Musashi accepts she and he are similar in that they can no longer be considered human. But they differ in that he travelled out of hate while she travelled out of a desire to be free. The group then fights Amakusa Shirou until he traps them in Shimabara Hell. From outside the Reality Marble, he boasts that Onrideo Castle is ready to activate. Upon hearing this, Muramasa forges Tsumukari Muramasa, and bisects both the Reality Marble and Onrideo Castle.
As the castle burns, Muramasa explains his sword could reach outside the Reality Marble because Onriedo Castle shares part of its name with Edo Castle. The name Muramasa is synomous with the Tokugawa's downfall, so Amakusa Shirou would have succeeded if he didn't rhyme the name of his castle with the Tokugawa's own. Kotarou then pierces Amakusa Shirou's heart with the kunai that Chiyome left behind. Amakusa Shirou is infuriated that his great works ends at the hands of a young ninja. Kotarou then finishes him off.
==Abilities==
Sherlock hypothesises he is an existence like a Mobile Singularity, something that anything and everything becomes possible with. It is this ability that allows him to travel between timelines. Being in the same world as Musashi, who is also akin to a mobile Singularity, will cause a number of abnormalities and unusual phenomena to occur such as the appearance of powerful monsters. Due to having a much stronger "mobile Singularity temperament" than Musashi due to being a more experienced traveler, he is able to control these abnormalities to an extent, such as controlling the monsters as minions. As an Avenger, Shirou Amakusa is an extremely powerful being, whose body has long since surpassed the limits of humanity becoming equal to that of a Heroic Spirit Swordmaster. Due to this, he is able to fight Senji Muramasa and Fuuma Kotarou at the same time without taking damage, albeit Muramasa was only wielding a "pathetic little knife". He also boasts the ability and sorcery to summon and corrupt Heroic Spirits stems from a being he calls "Satan."Fate/Grand Order: Epic of Remnant Shimosa: Section 15 Ultima Cantica: The Stage of Carnage, Onriedo (Ending)
In this form, Amakusa Shirou possesses the Shimabara Hell, a Reality Marble that reenacts the hell that he lived in the Shimabara Rebellion in which he was the sole survivor. The air inside the reality marble is highly poisonous and it would burn to ash the lungs of anyone should they take a single breath without being careful enough. Inside of it, Musashi feels useless due to not having anything to cut, and she no longer receives Lady Kannon's protection due to the marble being completely closed off.
It was ultimately destroyed by Muramasa's Tsumukari Muramasa. Shirou was shocked when this happened, and Muramasa explained it was because Onriedo Castle shares part of its name with Edo Castle. The name Muramasa is synonymous with the Tokugawa's downfall, so Amakusa Shirou would have succeeded if he didn't rhyme the name of his castle with the Tokugawa's own.
