''Manga/KarakuridoujiUltimo'' is known best for two things.

Being co-produced by Creator/StanLee, and its ''copious'' amounts of HoYay.

Then again, what else did you expect from a series with a minimal amount of female characters, [[CastFullOfPrettyBoys and many, many]] [[{{Bishonen}} pretty boys.]]

Expect some spoiler below.
-------------------

* ''Ultimo and Yamato.'' Takei really milked the whole master and page thing.
** Starting right at the second chapter was the infamous "glass-breaking glomp" scene. Would have been tame enough, except for Ultimo's unfortunate use of dialogue. It's even [[{{LampshadeHanging}} lampshaded]] by Rune.
** The entire ending of Chapter 3. Yamato stripping down to his boxers with Ultimo laying down on the bed. Comparing him to a ''fairytale princess'' and then deciding a kiss was the only way to wake him up. He doesn't kiss him in the end, but was still ended up in a compromising position. Ultimo woke up, and either, didn't see how suggestive the whole thing was, or didn't care.
** Chapter 4: Ultimo asking to wash Yamato's back. Hell the whole scene played out like a break-up if you get right down to it.
** [[DoesThisRemindYouOfAnything THE VOW.]] It's still is amazing how that got in a 13+ series.
---> Ultimo: [[InnocentInnuendo Please put your hand inside me Yamato-sama.]]
** When they are reunited the second time, their hug lasts a couple pages this time. Granted it was most likely due to the shock of Jealous transforming, but still.
** Ultimo's general dislike towards Lady Gekko, [[spoiler: and eventual murder,]] could be seen as this.
** There was also this exchange:
---> Yamato: How will I get back?
---> Ultimo: A gate.
---> Yamato: A ''date''!?
---> Ultimo: Gate. I will open up a temporary, space-time, gate.
** Frankly, Ultimo is just touchy-feely with Yamato the whole series.

* Rune and Yamato. More of a subversion though, since Rune actually does have feelings for Yamato.
** Pretty much count anything after his confession in Chapter 10. Although it's more of a deconstruction, due to Rune's [[AxCrazy unsettling]] [[{{Yandere}} personality]] [[LoveMakesYouCrazy change.]]
*** Especially in Chapter 21 with [[spoiler: the AttemptedRape.]]
** In the second bonus comic, Rune goes on a mini speech about how he'll always be by Yamato's side. Yamato is naturally [[{{ObliviousToLove}} oblivious]] to what Rune means.

* LesYay variant in one of the bonus comics. Oume was being hunted down by Akitsu because, well:
---> Akitsu: She flipped up my skirt!
---> Oume: [[LegFocus Your legs are so pretty!]] I wanted to see more of them!
