100 Anime Brother and Sister Relationships in Anime (Not Adoptive, Step-Siblings, In-Laws, Cousins)

In anime, brothers and sisters are a common theme, whether they are separated by years or are twins
Adoptive siblings are individuals who become siblings through the legal process of adoption. Example Edward and Alphonse who become adoptive siblings to Winry Rockbell after their parents' deaths from Fullmetal Alchemist
Step-siblings are children who become siblings as a result of their respective parents marrying each other. Example Yume and Mizuto Irido from Mamahaha no Tsurego ga Motokano datta
In-laws are relatives by marriage. This includes the siblings of one's spouse (brothers-in-law and sisters-in-law) and the spouses of one's siblings. Example After Naruto marries Hinata, he becomes the son-in-law of Hiashi Hyuga, Hinata's father. Additionally, Hanabi Hyuga becomes Naruto's sister-in-law.
Cousins are the children of one's aunt or uncle. They share a common set of grandparents but have different parents. Example Hinata and Neji Hyuga from Naruto

I forgot to mention Fuutaro and Raiha from The Quintessential Quintuplets. Regarding No Game No Life, I noticed that Sora and Shiro's parent and family details are not extensively explained. Therefore, I thought they were NEET biological brother and sister (or maybe there are some small conversations that I don't remember in Anime). Plus, it's pretty rare for someone to mention or post that they are step-siblings. However, in Sora's character detail on Anilist, MyAnimeList's synopsis, and both Shiro's and Sora's character details on MyAnimeList, it says they are step-siblings. If someone has already read the light novel, can they check which volume explains the step-sibling relationship? Thanks, and if you can, please type out the conversation.

It was mentioned in anime episode though. It's the literal plot points where Sora's gone and doing his trick. In that we seen the backstory that Shirou was introduced to Sora to became siblings. IIRC around episode 9/10

Bro you forgot Detective Conan characters too Akai Shuichi & Sera Masumi

[@nintendolife25]

I absolutely love the relationship between Tanjiro and Nezuko. Even when the latter is a demon and the former is against many odds to turn her back to normal, they still love each other and share such an unbreakable sibling bond. Easily one of the best sibling relationships.

Some mistakes! Sora and Shiro arent related, they step siblings Kirito and Suguha are cousins, she was adopted as his sister then.

[@NguyenQuynhAnhA-oz4og]
