We can say that it’s canon that Furuta would had a daughter.Do you have any headcanons about her? Like her birthday her name how she would look like her species her abilities and how her relationship would be with her papa?

– Furuta dotes on Miki. He treats her like his little princess. She is 100% a “Daddy’s girl.” 

– Her birthday is April 1.

– She probably has Furuta’s dark hair and delicate features, and hopefully Fruit-chan and his wife develop her mischievous side, too.

– If she’s mostly human, she might have stronger physical abilities, but not much more. She will not, however, inherit the shortened lifespan. 

– And Furuta will undergo the same treatment as Hsaio, so that he won’t have to leave his family anytime soon.

– Miki probably thinks her family is the best and her father very brave. Some day he will need to tell her the truth, and he fears that day. But I suspect Miki will forgive him.

– She WILL be best friends with Ichika.
