Tenma Siblings

Tenma Siblings is the family ship between Touya Aoyagi, Tsukasa Tenma and Saki Tenma from the Project SEKAI fandom.

Canon
Touya and Tsukasa attend Kamiyama High, whilst Saki attends Miyamaszuka Girls. Touya and Saki are first years, while Tsukasa is a second year.

In their early childhood, Touya had met Tsukasa and Saki through their parents acquaintance, those two becoming the first two people Toya respects. Though Tsukasa is infamous at Kamikou, Touya doesn't seem to mind. Akito was surprised when Touya mentioned Tsukasa as, "the upperclassmen who I respect".

Saki and Touya often played the piano together, but then drifted apart after Saki had been hospitalised.

Fanon
Tenma Siblings are one of the most popular family ships in the fandom, seeing how Tsukasa views Touya as a brother. Though aren't blood related, shippers often call out anyone who ships Touya with any of the Tenma siblings, calling it incest. There's a decent amount of fan art of the trio, with some of the fanart portraying their childhood memories. For those who ship the three in a poly ship, the ship is normally shipped as a solution to decide between TouKasa and Tousaki. Tsukasaki isn't normally shipped romantically due to the two being siblings. Most media often depict fanarts and fanfics of these three, either them bonding together or Tsukasa helping Touya escape from his father.

Tsukasa and Touya have a brotherly relationship, whilst people like to headcanon that the Tenma Parents had adopted Touya.

Mainly on Tiktok, people have often added Kanade into the Tenma Siblings, and in some rarer cases Haruka as well.
