==Abilities==
Abe-no-Seimei is regarded as the strongest and most famous Onmyouji of the Heian period. Even Katou Danzou heard his name revered during the Age of War some hundreds of years after his time. Due to this, no Onmyouji is believed to have ever surpassed him. He is supposed to be fairly well known in the Caster community. He is described as a legend that stands at the highest rank of Astrologers and a master of yin and yang techniques. It is even said that he knew secret Spells that could bring the dead back to life. It is also believed that a man with that True Name defeated the white-faced nine-tailed fox, one of the three great monsters that threatened all of Japan. Some stories describe him as a superhuman born to a fox, who went on to live an exceptionally long life. For all these reasons, Sherlock Holmes believes that it makes sense that he would leave his mark on Humanity as a Heroic Spirit.Fate/Grand Order: Epic of Remnant Shimosa: Section 14 Ultima Cantica: The Stage of Carnage, Onriedo (Middle) 
===Magecraft===
Abe-no-Seimei has displayed the following uses of Magecraft:
*Heian-kyō's Bounded Field: During 1008 AD, all of Kyo was protected by a Bounded Field created by Abe-no-Seimei to fend off invasions from powerful monsters. The field was formed by a layered barrier that reacted to the quantity of Mystics or possibly Magical Energy levels. The stronger the threat, the further away from the the Bounded Field would keep them when they materialize. During the Heian-kyō Singularity, the first two Hasshoujin appeared inside . Then, Saikyou Taira-no-Kagekiyo and Saiha Kugamimi-no-Mikasa showed up across from the Kamogawa at the end of . In Taisai Ibuki-douji's case, she was sent to Mt. Ooe, 100km northwest from Heian-kyo.Fate/Grand Order: Cosmos in the Lostbelt - Naraka Mandala Heian-kyo, Act 11 Genji Killer (First Half) Katou Danzou suspects that this Spell could easily surpass the power of relics from even the strongest ascetics. Alternatively, she speculates that it might use ashes from the Buddha, or something similar. The Bounded Field covering the city also worked as an enormous monitoring device that allowed Seimei to know what took place inside it better than he knew how clean his own house was. He could keep track of not just every event, but all conversations as well. Although this ability reminded Ritsuka Fujimaru of Lostbelt Zeus, Seimei claims that he is not that good.
*Mystic Eyes: Seimei claims he has Mystic Eyes capable of looking into the future. Thanks to this, he is fully knowledgeable of modern expressions which he used in everyday language as early as 1008 AD.
*: Abe-no-Seimei was able to create Onmyoudou talismans capable of temporarily sealing away the Souls of the Hasshoujin after their Spiritual Cores were shattered, preventing the Holy Grail in the Fantasy Tree Naraka Mandala from absorbing them.
*Long-Range Communication Spell: Abe-no-Seimei can project text on the air as a sort of written message. Medea Lily states that it is very different from telepathy and suspects that it is woven with a translation Spell as well.
*: One technique Seimei taught to Murasaki Shikibu, similarly named but unrelated to the , described by her as "like the embodiment of Lord Seimei’s desire to cause mischief has been materialized." It creates an invisible commentator that, unable to lie, "can target your heart and soul to give terrible wounds."
