Profile
"An assassin, but not at all ruthless. Every time a sharp blade is unsheathed, it's just to read a heart."

- Hakuja

There are big and small mistakes. Regarding the Snake Clan, the first small mistake was when choosing a test subject for a piece of not yet fully-developed enhancement technology, they selected the low-born Hakuja; while the second small mistake was making an outrageous miscalculation of strength with a boss’ wealthy second son as an assassin target. The big mistake after that was to directly judge Hakuja's assassination failure as an experiment failure; and the final fatal mistake was to prepare to dispose of the failed subject Hakuja, pushing this youth who just recently became the strongest assassin in the history of the Snake Clan towards the other side. After washing the Snake Clan's den with blood, the disoriented snake youth slowly walked onto the street for the first time, somewhat at a loss. However, he very soon got to know new friends- a cute yet arrogant cat girl who enjoys observing humanity; after that the former assassination target also brought him a new job. 错误有大有小，对于蛇族来说，第一个小错误是为一项还不成熟的强化技术选择试验品时，选中了出身低微的库伽；而第二个小错误则是对作为暗杀目标的富家二少爷做出了错误到离谱的实力判断；接着的大错误是将库伽的暗杀失败直接推定为实验失败；而最后致命的错误就是准备将失败品库伽处理掉，将这位刚刚成为蛇族有史以来最强刺客的少年推向了对立面. 血洗了蛇族巢穴之后，蛇生迷茫的少年第一次慢慢走在街上，有些不知所措. 不过他很快结识了新的朋友——可爱又傲娇、喜欢观察人类的猫娘，接着曾经的暗杀目标也给他带来了一份新的工作.

Lore

 * Hakuja can control his venom. His waist pouch contains his and Weizi's freshly extracted venom.
 * As a snake, Hakuja can swallow things far bigger than him. But now that he has a human form, he's decided it won't be polite.

Storyline

 * Hakuja was ordered by an unnamed man to kill Yomiya. He did not, claiming he had no interest, though the truth may have been that Kamiya (Yomiya's alternate personality) was stronger than him. At this point, he had also realised that Yomiya’s death would cause panic which the man can take advantage of and take control. Since he knew too much now, the man pressed a button on a remote controller, causing acid to corrode Hakuja's mechanical system; there was a bomb bound to his core. However, Hakuja was not defeated.
 * Around 23:08 on an unspecified day, the bomb fragments were removed from his sea of consciousness through a card reader and computer accessing his consciousness, with the help of an unnamed person (POV of his self-introduction video) on the order of Black double ponytails and his emotional state returned to normal.
 * During his debut stream, Hakuja received an anonymous message telling him that there was a bomb planted inside each of his gen-mates, and that all five of their bombs will explode in 30 minutes. He managed to disarm them in time.

Miscellaneous

 * Hakuja used to have long hair, but cut it after it got too inconvenient.
 * Hakuja can do a very convincing girl voice, known as his younger sister 库佳 (Kujia).
 * Her name uses the same first character as Hakuja's Chinese name while the second character means good/beautiful (common in female names).
 * Her emoji is the comet (☄️).
 * Hakuja's underwear and earphones were stolen in transit while moving to his new home. While relating the story on stream, he accidentally revealed the colour (purple, blue and grey). Since then, "purple underwear" has become a running joke among his fans.
 * The first VTuber Hakuja ever saw was Eine, which was how he got to know VirtuaReal.
 * Four months before Hakuja debuted, he knew of Keke’s existence due to a member of staff letting it slip. He had asked them if Yomiya was the Deer Clan's prince, to which they replied, "No, not a prince. The prince is in the next wave."
 * From the fifteenth wave onwards, Hakuja has a tradition where he edits the silhouette teasers of upcoming waves.
 * For 167, after taking inspiration from Kouichi's comment, he replaced Karisa with Mahiru, Kiyuu with Nyatsuki, Girimi with Hoshimi and Kiyuu with Rhea. It managed to briefly fool Yomiya into thinking it was the real one. Hakuja got questioned by staff after posting it into VirtuaReal's group chat.
 * The iconic slap effect in Hakuja's self-introduction was performed twenty-something times and chosen from the best one.
 * He was only given three hours to make his self-introduction. He had wanted to add better effects but didn't have the time.
 * Hakuja mentioned during his birthday stream that he had planned to graduate in March due to health issues, but remembered the things he had not yet shown his viewers and wanted to give himself another chance. He has elaborated on his health issues multiple times on stream, which include intestinal and breathing problems.
 * The main reason for his health issues is due to the fact he was in breech position at birth, causing him to choke on amniotic fluid and be strangled by the umbilical cord. His mother had to get a caesarean.
 * Though Hakuja thinks he’s unfortunate, he is glad he’s at least alive, which is why he especially enjoys life.
 * Hakuja's character designer had to add a black undershirt to his design after staff said it was too immodest.
 * Hakuja is particularly close with his mother, phoning her many times every day.
 * Hakuja has a friend referred to as 兄弟A (Brother A), who he sometimes plays games with on stream.
