Kankitsu Akitsuki in Naruto

When Kankitsu and Remon were kids, they grew up together but things changed when Kankitsu turned twenty. A strange curse mark appeared on his right palm. To control this curse for a hundred more years, Kankitsu was told he had to marry Remon.

Kankitsu went to the Yoimura family to talk about when the wedding should happen. However, a tricky character named Soma convinced him to touch a mysterious rock. This rock had a demon inside, and it took control of Kankitsu. Because of this, he started acting distant and unfriendly toward Remon.

As Kankitsu and Remon were getting ready for their wedding ritual, two people, Konohamaru Sarutobi and Boruto Uzumaki, came to see them. They wanted to return a handkerchief to Remon, which she had lost in their village, Konohagakure. Kankitsu, acting very polite but insincere, asked them to leave.

Later, Kankitsu did something strange as he put Remon in a small room and said it was for her safety. He also took away her special hair clip. When he noticed that someone named Asaki was getting suspicious of him, he went to her and erased her memories to keep her from knowing too much.

After that, Kankitsu went to a sacred shrine where a demon named Sōma was kept. He seemed pleased with how his plans were going. He wanted to destroy Remon's hair clip, but Asaki stopped him, knowing it was important. Kankitsu thought Asaki was a problem, so he used the power of Soma to deal with her. But Boruto showed up to protect Asaki.

Kankitsu erased the memories of both Boruto and Asaki. However, Boruto managed to keep the hair clip and escape. Kankitsu decided not to chase him because the hair clip was now with Boruto, and it was no longer a problem. He then told Remon they would have the wedding ritual the next day.

During the ritual, Kankitsu was supposed to use a sword to cut off a growing horn, but instead, he used it to destroy a seal. This caused Soma to break free from his control. When Kankitsu woke up and realized what he had done, he was horrified.

Remon, despite losing her memories, helped Konohamaru and Boruto to finally defeat Soma by sealing it inside her. This came at the cost of Remon's memories. But Kankitsu was determined to rebuild their relationship by helping her remember everything.

At first, Kankitsu was a kind and happy person who always smiled while playing with Remon. But when Soma took control of him, he became cold and distant. He started acting like he knew everything and became very bossy. After Soma's influence was gone, Kankitsu returned to being his original, friendly self.

Kankitsu has messy red hair, and his eyes are beige with black pupils. He has a fair complexion. His attire includes a black business suit, a gray collared dress shirt, and a light violet necktie. However, when he was under Sōma's control, his eyes lost their pupils, and they appeared blank.

When Soma had control over Kankitsu, he could create a white aura. If he touched someone, he could take their memories. He could also send out energy blasts from a distance to steal people's memories.
