Keisara

Keisara is the het ship between Keiji Shinogi and Sara Chidouin from the Your Turn To Die fandom.

Chapter 1, Part 1
After the Death Game starts, Keiji wakes Sara up, making him the first character that Sara meets when the full cast is introduced.

Chapter 1, Part 2
In Chapter 1, Part 2, Keiji and Sara unofficially partner up to investigate.

Chapter 2, Part 1
In Chapter 2, Part 1, Sara is tormented by her self-imposed hallucinations of Joe and the other dead victims of the Death Game.

When Keiji tells her that she should get some rest, Sara tells him that she doesn't want to sleep. The player has the option to ask Keiji to stay with her or tell him that she wants to move around. Regardless of the player's choice the end result is the same, in which Keiji offers his shoulder to Sara.

Chapter 2, Part 2
In Chapter 2, Part 2, the Second Main Game begins, and the surviving cast must deal with the new forcible trading phase.

When the group is escaping up the Long Stairs, the topic of what everyone wants to do when they escape comes up. Keiji wonders out loud what he wants to do after getting his freedom back and the player has multiple options to respond with. One option involves Sara telling Keiji that he should find something worth doing. This leads Keiji to thoughtfully respond that maybe he should find a reason for living, to which Sara immediately replies that she'd be glad to assist. Keiji is noticeably taken aback until he realizes Sara is unaware of the secondary meaning behind her literal statement, and thanks her, much to her confusion.

General
Keiji occasionally calls Sara "cute", usually to deflect from answering her questions properly. However, he also often flirts with Sara without prompting, and other characters have commented on his flirtatious remarks toward Sara.

Your Time to Shine
In Mishima's Route, in Keiji's First Fondness Event, Keiji asks to drink with Mishima, and when Mishima hesitates and plans to refuse, he offers to drink with Sara instead, despite her status as a minor who is not legally allowed to drink alcohol as she is under 20 years old. Mishima points this fact out and Keiji lazily asks if the laws apply on the island, which is enough to make Mishima hurriedly take his offer.

In the case that Sara has died before the event, rather than choosing a different underaged character to threaten Mishima with, Keiji insteads holds himself hostage in order to persuade Mishima.

Fanon
Keisara is by far the most popular ship in the Japanese fandom, while it's somewhat controversial in Western fandom spaces due to the age difference between the two characters.
