AiViku

AiViku is the het ship between Eins and Victoria Frankenstein from the Victoria's Electric Coffin fandom.

Canon
Victoria Frankenstein is the creator and caretaker of Eins, the Electric Coffin. She is shown to have a great deal of pride in him as both her invention and as a friend. In turn, Eins is shown to have a great deal of respect for Victoria and is seen striving to meet her expectations.

In addition to his admiration of her accomplishments, Eins seems to find Victoria beautiful in some regard. He is shown multiple times thinking of her as an angel, though is shy about saying so aloud. Victoria interprets his cut-off declarations of "a...g..." as Eins referring to her as "a genius."

During the Award Ceremony for Victoria's achievement in the Electric Coffin's creation, Eins gifts her a bouquet of red, white, and purple anemones. In hanakotoba, the Japanese language of flowers, red anemones mean "I love you," white anemones mean "anticipation," and purple anemones mean "I believe in you." Victoria accepts his gifts and teases him, saying that it feels like they are at a piano recital.

Towards the end of the series, Eins finds Victoria's diary, in which she writes about Eins and his accomplishments. She confesses that one of her goals in creating the Electric Coffin was to teach him about love, and that if he would allow it, she wished to spend the rest of her life with him. At reading this, Eins rushes to stop her from leaving for Germany.

The end of the series shows Eins and Victoria moving to Switzerland together. In the timeskip epilogue, an older Victoria gifts a bouquet of purple tulips to Eins during their trip back to New York. In hanakotoba, purple tulips represent immortal/undying love.

Fanon
Fan reception of the ship has been generally positive, for both romantic and platonic interpretations. Those who do not see the relationship as romantic tend to view Eins and Victoria as having a sibling-like dynamic.

Trivia

 * In response to a fan's comment, the author, Tajima Ikuno, stated that she intentionally used a bouquet of four tulips in the series's final chapter, as four flowers can also mean "I want to spend the rest of my life with you."
