He is more emotional than Inuyasha but he hides that fact by rubbing his eyes or diving and swimming underwater when he wants to cry. He is a diligent genius which allows him to quickly learn how to use a sword just by listening to his grandfather’s instructions. He used to be extremely antisocial but in modern days, he’s just antisocial to those he’s not close with. He refers to his family members using formal terms, for example, he refers to Inuyasha as “aniue”. He is meticulous when it comes to taking care of himself, like combing his hair for example. He appears to be cold but is very caring. He easily has crushes on attractive dog demonesses in his clan. 

He can fall asleep easily, is more openly affectionate in intimate moments compared to his brother, is diligent which is seen in his studies and physical training, he is intelligent but has trouble with being social with those who aren’t part of his family.

Background

Inuyasha and Inuyōsei were born on December 4th, 1294 on a lunar eclipse to a dog demon father named Tōga and a human princess named Izayoi. Two months later, the lands of Izayoi's father were dominated by other lords who were envious of Izayoi's father in a combined effort and Izayoi and Mizuki, a dog demoness who served the twins' grandparents and Izayoi's midwife, escaped in a carriage. However, some people caught up to the carriage and shot arrows at it. Izayoi had been holding one baby in each arm and when the force from the arrows made the carriage tilt, Izayou's grip on Inuyosei loosened and Mizuki jumped out after Inuyosei. Izayoi hit her head and blacked out. 

The carriage kept moving forward and left Mizuyki and Inuyosei by themselves in the woods. Mizuki was holding Inuyosei while rolling down the cliff. She used her wind powers to keep him from falling which made him sickly for 10 years. She blacked out and she and the infant were found by Sesshōmaru and his hidden guard. Mizuki and Inuyosei were brought before Kimi, Sesshōmaru’s mother.

4 years later, the human guards finally reported to Izayoi about Takemaru no Setsuna's death at the hands of a demon. Devastated by the loss of her lover and child, she gradually weakened away out of grief. Inuyōsei was brought before Izayoi when she was on her deathbed. She said her last words to her children and passed away.

Unfortunately, when Inuyasha was brought to the white dog demon clan, he was chased out by members of the clan for they despised him for his half-human heritage. Inuyosei, on the other hand, had already been living with Kimi so they could not do the same to him. Now, that Inuyosei learned that his immediate family was not Kimi and Sesshōmaru, he told Mizuki that he wanted to leave Kimi’s palace. His caretaker agreed with his wishes and while Inuyasha was being chased out by the clan, Inuyōsei was chased out as well. His grandfather’s underlings were sent to recover Inuyasha and mistook Inuyōsei for Inuyasha. Mizuki followed them. 

When Inuyōsei arrived at his grandparents’ castle, they realized their error. Yuudai sent his underlings to search for Inuyasha again. From then on, Inuyōsei lived with his grandparents and Mizuki resumed her service under them. He eventually went to look for his older brother when he was 100 years old. He and his older brother ended up falling in the Spring of Youth in a battle with a Chinese Emperor who wanted the power to stay youthful forever and wanted to go after the swords of his elder brothers to gain passage to the Spring of Youth in the Underworld. The Spring of Youth made them enter a long sleep until modern days.

Relationships

Family

parents – Tōga and Izayoi (deceased), grandparents – Yuudai and Tsukiko (deceased), older half-brother – Sesshōmaru, stepmother – Kimi,  younger twin brother – Inuyosei, nieces – Towa and Setsuna

Inuyōsei and his older twin brother received their names from their father, the dog demon lord, Tōga at birth. Unfortunately, he died shortly after protecting them and their mother from a samurai named "Takemaru no Setsuna" who also had feelings for their mother so the twins don't have any memory of him. They are aware that he was a powerful demon and Tōga left his treasure sword, Tessaiga, to Inuyasha after his death which allows Inuyasha to keep his demon blood in check. Inuyasha was raised by his mother but Inuyosei was separated as an infant so Inuyasha has more memories of her out of the twins. Inuyōsei yearned for a mother’s affection but when he saw her for the first time, she was playing happily with Inuyasha which made him disappointed with her. He resented her for dying and finally showing him that she cared about him. But, when his grandmother, Tsukiko, gave him the kimono that his mother made for him, he began to stop hating her. 

He calls them “Oji-sama” and “Oba-sama.” He used to be extremely antisocial towards his grandparents until the age of 50 when he finally opened his heart to them. When he was 50 years (appears 10-12 years old), his grandmother found the kimono that his mother gave him and gave it to him as a birthday present. After receiving the present, his health began to drastically improve, his grandfather gave him a katana, and taught him sword techniques. When he turned 100 (appears 15), his grandfather gave him his sword, Getsuga, when he announced his wish to go look for Inuyasha. 

His older brother, Sesshōmaru, has a different mother and is full demon. He resents the twins for their tainted human lineage aside from being the cause of his father's death. Ironically, he does become the father of half-demon daughter twins himself and Inuyasha and Inuyōsei are good uncles towards his daughters. Inuyōsei was initially jealous towards him because it looked like Izayoi loved him more. He felt duty bound to uphold the promise between him and his deceased mother to search for Inuyasha. He gradually comes to care for and love Inuyasha a lot and the feeling is mutual.

Love Interests

Vanessa Nguyễn aka Sailor Styx

In their previous lives, they met during Princess Serenity and Princess Tranquility's 14th birthday ball. When the attendees were asked to dance with someone from another home celestial body, Vanessa found herself staring at Queen Serenity's second prince, Prince Lucius and the prince smirked at her when he caught her staring before bowing and invited her to dance. Vanessa shyly accepted his invitation and they spoke during and after the dance then kissed in the rose gardens of the Moon Castle. They reunited during modern days when Sailor Styx was separated from her team, and she was forced to cooperate with him. She remembered him from their past lives, but he didn't. His cold attitude and curt manner of speaking put her off but since they're both of supernatural and mixed human lineage with sharp noses, they were able to connect their civilian forms to their alter egos because of their scents. As they cross paths with one another, Inuyosei finds her to be endearing and Vanessa sees a more caring side to him. As they fall in love all over again, Inuyosei eventually recalls his past life memories and his previous romance with Vanessa's past incarnation. When Sailor Styx was weakened, Selene Knight bridal carried her in front of all the Plutonian Guardians. When he is 18 on documentation, they get married.

Inspirations

Since Inuyōsei is pretty much Inuyasha's twin, he had to have music from the show in his soundtrack. Older episodes depict Inuyasha with a lighter complexion so I wanted that for Inuyōsei. Thanks to the Inuyasha wikia for helping me describe his  abilities.
