* The series sometimes takes the FoeYay between Masamune and Yukimura to ridiculous heights. After their first fight Yukimura was left [[LoveAtFirstSight literally weak in the knees]], they're always [[OrgasmicCombat so into their matches]], they spend the majority of the show thinking about fighting each other and Sasuke even comments that they might have "fallen" for each other from their first fight. In episode 10, when Masamune went to grab Yukimura's necklace, half the fangirls/fanboys were expecting him to just kiss Yukimura there and then, genre be damned.
** And in the second season the necklace-grabbing scene turns up in ''both'' of their flashbacks about each other, while Yukimura fanboys Masamune and Masamune speaks fondly about Yukimura being "pure" and "out of this world, no kidding" and "so fiery I can't get away with only a burn"...
** The handshake scene from the second OVA competes with the necklace grabbing one in terms of sheer HoYay, a CM for the movie has Masamune declaring that Yukimura is the only one who can really heat him up, and in an article about the movie we have the ''director'' emphasizing that Yukimura is the most important to Masamune.
** ''Moonlight Party'' is just as bad, with the guys spending an episode chained together thanks to Mitsuhide, Masamune cooking for Yukimura and Masamune's rather...extreme reaction when Yukimura [[spoiler:apparently sacrifices himself to save Masamune from the bomb]].
** Creator/KazuyaNakai said their battle in the movie was referred to as a love scene. Make of that what you will.
*** To which Creator/ToruOkawa remarked that Ieyasu and Mitsunari were no less passionate about each other...
** On a creepier note, there's the relationship between Uesugi Kenshin and Takeda Shingen. Though since [[ViewerGenderConfusion it was rumored that the real Kenshin was actually a woman]] and this Kenshin [[ShrugOfGod may actually be one]], this might also count as LesYay between him (her?) and Kasuga.
** CombatSadomasochist Akechi Mitsuhide's fights with any of the male cast members, especially Kojuro, count, but mostly because [[BloodKnight he's way]] [[SexIsViolence too into it.]]
* The ''Sengoku Basara'' anime takes this trope and [[UpToEleven runs with it]]:
-->'''Yukimura:''' Burning.
-->'''Sasuke:''' ...[[FlatWhat What]]?
-->'''Yukimura:''' My heart is burning. Such presence. Such fighting spirit. Such... strength.
-->'''Sasuke:''' Er, please don't tell me he lit your soul on fire.
** It's even more obvious (and lampshaded by Sasuke) in a later episode when Yukimura and Masamune reflect on how badly they want to fight each other.
--->'''Yukimura''': The one I really want to fight is Date Masamune, the One-Eyed Dragon!
--->'''Sasuke''': You really fell for each other...
** In the second season they fanboy each other in what can only be described as daydreams. In the last episode Masamune even seems to sense when Yukimura goes down.
** Even ''Judge End'', the newest season, does not let up at all, with Masamune having dreams about fighting Yukimura and declaring that he is the only one who can set him on fire. Oh, and Yukimura is surrounded by ''sparkles''.
** You ''know'' you've got serious FoeYay in your anime/game series when even the ''[[http://community.livejournal.com/sengoku_basara/122440.html T-Shirts]]'' come off as slashy.
** Masamune and Yukimura sit on the fence between FoeYay and simple HoYay, because while they ''are'' enemies who will one day probably fight to the death, they actually like each other, enjoy fighting each other, and outside the battlefield they get along pretty well.
* In ''[=SB3=]'', in Motonari's stage while playing as Mitsunari, he will refer to Mitsunari's "lover's spat" with Ieyasu.
* Hideyoshi and Hanbe's relationship. Their devotion and general affection for each other is easily interpreted as this.
