ZofiKoko

ZofiKoko is the het ship between Zofis and Koko from the Zatch Bell! fandom.

Their first meeting
When they first met, Zofis needed Koko as partner for the battle to decide Mamodo King, because only she could read Zofis' book and make him able to use his spells. But Koko wasn't interested in neither battles nor power and refused to help him. Then Zofis used his mind-controlling powers on her to force Koko to become his partner. He increased hate and envy that was hidden in the deep of her heart, he made her forget things that he didn't need for the battle, and made her obsessed with power.

Then Koko burned her village, where she has been discriminated all her life, and attacked her friend - Sherry. Then, together with Zofis, she left the village.

During the Zofis Arc
Koko has changed and abandoned her old life and dreams. She went to live with Zofis in the castle of Devolo ruins in Peru, where Zofis' army was based. Gradually, she became not only perfect violent partner who obsessed with power and battles. She developed an affection and attachment for Zofis. She spent all her time with him, hugged him and complimented him. In general, Koko lived with Zofis about one year from their first meeting.

When Zofis' army was defeated, he had to face Brago and Sherry in battle. Zofis used Koko to kill morale of Sherry. Together, they convinced Sherry that everything Koko does is not forced by Zofis - these are Koko's true feelings and her true self, and Zofis only helped Koko to become herself. They managed to convince Sherry to believe them, when Koko showed necklace she pretended she stole from Sherry's house when they was children, and made Sherry incapable to fight. In reality, this necklace was recreated by Zofis from Koko's memory. But then, Sherry's mamodo Brago helped Sherry, and she stopped listening to Koko's words and successfully attacked Zofis and immobilized him. She continued to attack him, despite Koko's screams to not take Zofis away from her. Now that nothing helped, Koko jumped from the cliff to try to save her mamodo Zofis. Zofis was freed from Brago's spell, and Koko continued to read spellbook, while she fell from the cliff, so Zofis could attack again. But Sherry managed to save Koko from falling and defeat Zofis.

Koko and Zofis were defeated. Koko passed out, and Zofis, despite he was heavily damaged and almost immovable, started to smile. He told Sherry that they will not return Koko's happiness. He controlled her emotions and changed her personality, but still she had her own will. If Zofis' book will be burned, Koko's personality will return, but she will remember everything she did with Zofis, and she will never forgive herself. But Sherry already knew it, she began to demand from Zofis to erase Koko's memory. But Zofis refused and just laughed at Sherry. Then, Brago intervened and threatened him, and Zofis got scared and cried. He apologized and promised to erase Koko's memory. After he did it, his book was burnt.

After the end of the battle to decide Mamodo King
After the end of the battle to decide Mamodo King, Zofis was shown smiling on the group photo that was sent by mamodos to they partners. But most likely Koko did not received the letter from Zofis, because she no longer remembered him, and he is afraid of Brago so much, he would not risk to do it.

Zofis also appeared in the omake "Gash Café". Unlike for other mamodo, his waitress was not his partner, Koko, but a Koko-looking robot. He also said that the real Koko would never see him again.

Despite this, Zofis appeared together with Koko on the cover that was released after "Gash Café" with him. On this cover Zofis stands close to Koko, who is not under his control, as if nothing had happened. Although before that, after the end of the Zophis Arc, the author never drew them nearby, and always put Koko next to Sherry, and Zofis to the opposite corner.

Сonclusion
Koko, when she was controled by Zofis, showed much more attention to him than he did to her. Perhaps, she considered him good-looking, and it was used to increase her feelings in something more than just attraction.

At first glance, it seems like Zofis only used Koko as a tool to achieve his goals, as he was willing to risk her life and future. But, on the other hand, it was he who made her so affectionate to him, and it was not necessary for for the battle. So, for sure, he has some attraction to her.

Fanon
ZofiKoko is not a very popular ship, however there is enough variety of their relationships in fanart. The most common is:

Standard ZofiKoko in which Koko has two separated personalities and while one personality is dark and enjoying her time with Zofis, the other, normal personality inside Koko suffers from it. This type of relationships is the most similar to original.

ZofiKoko in which the normal personality of Koko don't appear, or dark Koko is an only real Koko's personality.

ZofiKoko with alternative story in which Koko agreed to help Zofis and became his partner without him using his mind control powers on her.

ZofiKoko in which dark Koko don't like Zofis. It's sometimes happens because Zofis made Koko evil, and she became evil even to Zofis (unlike in original, where she liked Zofis), or evil Koko still prefers Sherry over Zofis. It's mostly gags without romantic.
