DrakEmma

DrakEmma is the het ship between Ken Ryuguji and Emma Sano from the Tokyo Revengers fandom

Toman Arc
They are first seen when Draken calls Emma over to take Hinata Tachibana with her, whom Takemichi Hanagaki had on top of him earlier. After Hinata finds this out and beats Takemichi up, Emma explains that she only went after him just so Draken could feel jealous because she wanted for him to pay attention to her. With that, she solemnly walks away to Hina.

Moebius Arc
Emma is later seen crying as she explains to Takemichi how Draken and Mikey ended up in an argument which resulted in Toman splitting into the Mikey faction and the Draken faction, seemingly worried for Draken. They later share a seen in which Emma is tugging Draken towards a stand begging while Draken is unamused, which Hina encourages Emma to not give up.

Draken and Emma are later seen walking in the rain, and are approached by Peh-yan. Draken is stabbed later on by Masataka Kiyomasa, and when he was on cardiac arrest, Emma is shown crying on Hina's shoulder for his well-being. Emma is relieved after she and the others were told Draken survived.

Valhalla Arc
After Takemichi leaves the brothel Draken lives in, he thinks about how Draken has a picture of Emma along with everyone else he cares about, which was the first implication of Draken's feelings for Emma being mutual. As Takemichi is cheering for Emma to pursue Draken, he happens to see her and walks in to greet her until he sees Emma hug Mikey affectionately, causing him to misunderstand the situation, thinking Emma is cheating on Draken with Mikey and wonders what would happen if Draken found out about it.

Hina shows up as well, along with her brother Naoto, and knowing that Emma likes Ken, she decides to solve the mystery. Draken later shows up, much to Takemichi's and Hina's shock, until it was revealed Mikey and Emma were siblings. Draken then gives Emma a plush toy; the one which Emma payed attention to at an arcade the other day, and he wishes her a happy birthday before leaving. Emma is seen hugging the toy and smiling happily.

Black Dragon Arc
Emma and Draken aren't given many moments during the Black Dragon Arc, but they are seen together along with Mikey during Shichi-Go-San. They jump alongside everyone else after the countdown.

Tenjiku Arc
At the end of Chapter 123, it shows Emma meeting with Draken, strutting towards him as she apologizes for making him wait.

Later on, Emma is struck in the head with a metal bat by Tetta Kisaki. As Mikey carries Emma to the hospital, a dying Emma asks Mikey to tell Draken that she loves him. When she goes limp, Mikey goes on to say that Draken loves Emma too, although he promised not to say anything about it. Panicking, Mikey goes on to ramble about Draken and Emma's future; they both have a child, Draken builds a small house to live but it gets messy. Then Draken woukd invite Mikey, and also Takemichi and Mitsuya and they would talk about their teenage years, but the noise would wake the baby up and Emma woukd scold Mikey.

Draken is shown in despair when he looks at the corpse of Emma, and beats up Mikey for not protecting Emma.

Bonten Arc
In Emma's funeral after the Kanto Incident, Draken apologizes to Emma's grandfather for not protecting Emma, and sobs as Grandpa Sano tells him she must be resting now.

Even after twelve years, Draken still loves and misses Emma dearly, shown when he reads out loud his letter he write for the future him, stating at the end of his letter that "Emma will always be with you".
