''Love Stage!!'' is a BoysLove manga created by Zaou Taishi and Eiki Eiki, running from 2010 to 2016 in ''Asuka CIEL'' magazine. It received a 10 episode anime adaptation in the summer of 2014.

Sena Izumi is an {{otaku}} in a family full of entertainers; his mom is an actress, his dad a singer, and his older brother a member in the famous music group Crusherz. His family wants him to join the entertainment business, but he doesn't want any of that, instead he wants to be a mangaka. But when he reunites with Ichijou Ryouma, an up and coming actor who had fallen in love with him when they did a commercial together as children, it seems like his family will get their wish.

''Love Stage'' also has a side story by the name of ''Back Stage!!'', which is a novel about Izumi's older brother Shougo and Sena's Production manager Sagara Rei. That novel eventually got its own manga adaptation in ''CIEL''.

A live-action adaptation came out in 2020, with another (this time a Thai production) to follow in 2021.

* GenderBlenderName: Izumi's name is androgynous and is more feminine than masculine, which also helps with Ryouma's initial confusion of Izumi's gender. Rei's name is also traditionally feminine.

* TheGlomp: Izumi does this in Episode 10 to Ryouma and in the anime's opening.

* HappilyMarried: Seiya and Nagisa, the parents of the Sena brothers, are very much in love and happy with their marriage.
* HardWorkHardlyWorks: In the acting world, where relatives of already established celebrities break out much easier, Ryouma worked really hard to [[DefiedTrope defy this and succeeded.]]
** [[spoiler: To his horror though, Izumi played this straight and had more than enough talent at acting to make him feel inferior.]]
* HeroicBSOD: Izumi, after trying to enter his manga into a contest and being told he has no talent. Ryouma helped him by giving the manuscript to Izumi's favorite author and begging him to give Izumi's work constructive criticism. Later on, Ryouma has his own moment, when [[spoiler: Izumi floors him with his superior acting ability, proving himself a complete natural, in his very first acting gig, and Ryouma is affected so badly that he is unable to focus, forcing Director Kisaragi to attempt his hypnotism trick on Ryouma, to calm his nerves. [[FromBadToWorse Unfortunately, the hypnotism proves ''too'' effective,]] [[LaserGuidedAmnesia as Ryouma ends up forgetting]] not about his worries but the ''source'' of his worries: Izumi, even to the point that the hypnotism undoes their past progress, as Ryouma cannot even remember Izumi from when they were kids--which is a huge deal, considering the effects that first encounter had on Ryouma for the last 10 years.]]
* HypocriticalHumor
* OhCrap: Ryouma when he sees how good of an actor Izumi is.
* IfItsYouItsOkay: Stated word for word by Izumi.
* IHaveThisFriend: Izumi, when asking Rei a question about sex.

* LeaningOnTheFourthWall: Izumi was worried that he was an uke in a BL manga.
* LightningCanDoAnything: In the Extra Stage, an electrical storm broke out across the whole of Tokyo, and switched around the bodies of anyone who happened to be touching. First with [[spoiler: Ryouma and Izumi]], then [[spoiler: Shougo and Rei]]. Then after [[spoiler: Ryouma and Rei]] are returned to normal, it happens again to [[spoiler: Izumi and Shougo.]] [[spoiler: It turns out to be AllADream, courtesy of Kisaragi.]]
* LoveEpiphany:
** Ryouma realizes he's still in love with Izumi when he sees him naked and is overcome with desire rather than disgust (though, Ryouma never fully did lose his feelings for Izumi when he learned he was a guy) and Izumi has one for Ryouma when he is being violated by three men and he says to himself that he doesn't want it if it's not with Ryouma.
** Similarly, [[spoiler: Rei realizes he's genuinely falling in love with Shougo after being attacked by a stalker and realizing that he only wants Shougo to touch him]].
** It's implied at the end of the manga that [[spoiler: Kuroi finally reciprocates Saotome's feelings]] though we don't get to see how this plays out.
* LuminescentBlush: Whenever one of the characters starts blushing, it's often this.
* MagicFeather: Ryouma's magic charm was just a marble that resembled Izumi's eyes and the hypnotism performed by the director was also fake. These were just tricks to get rid of Izumi's performance anxiety.
* MultiGenderedSplitPersonalities: Invoked. The protagonist Izumi, an otaku from a prominent family of actors and music talents, is [[ShowWithinAShow cast in a TV Drama]] as the main character, a rich young master with three personalities, one of which is a girl. This difficult role shows off Izumi's prodigious but heretofore unseen acting abilities, causing feelings of inadequacy in his senior co-star and boyfriend, Ryouma.
* NakedApron: Rei dresses up in one for white day [[EpicFail after he failed]] to bake a cake.
** {{Cosplay}}: What Rei ends up doing for every holiday, including a {{Meido}} outfit.
* NearRapeExperience:
** [[spoiler: In chapter 4-5, Ryouma strips Izumi in order to prove to himself that Izumi is a man. He realizes he still likes him and almost goes too far before Shougo comes to the rescue.]]
** [[spoiler: Happens to Izumi again in chapter 14, with some thugs...Izumi has no luck.]]
** [[spoiler: With Rei, he gets a stalker and is almost raped until Shougo comes to the rescue.]]
* NoCelebritiesWereHarmed: Shougo is obviously based off of Daigo from the band Breakerz.
* NoseBleed: Ryouma got two nosebleeds in Chapter 9 all due to Izumi. This is after he walks in on Izumi naked in the bath and again when he sees him [[SexyShirtSwitch wearing Ryouma's oversized shirt.]]
* NoSympathyForGrudgeholders: Izumi is known for holding grudges, 3 weeks being his record, so when he and Ryouma have an argument on set, Rei just tells him to get over it and make up with Ryouma so they can continue filming the show.
* OfficialCouple: Ryouma and Izumi, Shougo and Rei.
* OneHeadTaller: Ryouma is a little more than a full head taller than Izumi. Averted with Shougo and Rei, as they are about the same height.
* OnlySaneMan: Rei serves as this in the Sena household for the most part.
** [[spoiler: Kuroi from the manga club is the only one who actually sees through the "[[ClarkKenting disguises]]" Ryouma and Izumi have.]]
%%* {{Otaku}}
* OutfitRipSexCheck: Shougo rips open Izumi's dress to show Sena that Izumi is actually a guy.
* ParentalSubstitute: Izumi says that as a child, his parents were busy, so Rei and Shougo were like a second mother and father to him.
%%* ReplacementGoldfish: What Shougo starts as with Rei.
* TheRival: Shougo to Ryouma.
* RunningGag:
** Izumi locking himself in his room when he's upset about something and Rei kicks in the door.
** Izumi trying to top Ryouma.
* SacredFirstKiss: Izumi freaks out when Ryouma kisses him (Izumi didn't know about the scripted kiss) while filming the second commercial, and Izumi locks himself in his dressing room. He wanted his first kiss to be with a girl like Lala Lulu.
* {{Seme}}: Shougo and Ryouma. Izumi tried being seme in Chapter 16 after being convinced by Rei to "turn the tables" on Ryouma after Izumi tells Ryouma that he was hurt pretty bad after their first time; when it got to the point of actually having sex for the second time, Ryouma took his place as seme. [[spoiler: In the most recent chapter, Izumi decides the best way to win Ryouma back after he gets hypnotized and loses his memories of Izumi, is to study all types of semes and have sex with Ryouma with Izumi as the seme; this finally happens at the end of the manga, though Ryouma hardly feels a thing!]]
* SexyDiscretionShot: The anime. When things are getting a little too heated for television in the bedroom, we get a nice tour of Ryouma's kitchen cabinets instead.
* ShipperOnDeck: Rei tells Izumi that he approves of Ryouma because he thinks he's a good guy.
* SingleTargetSexuality: Ryouma says as much. Shougo has been in love with Rei ever since he met him in the Back Stage novels.
** In a joke WhatIf issue which featured a CrossOver with ''Manga/RenaiIdenshiXX'' (where the characters live in a BadFuture where men no longer existed), Izumi and Ryouma reject the advances of the women, with Ryouma saying that Izumi is the only one for him and Izumi saying he wants to marry a girl like [[ShowWithinAShow Lala Lulu]].
* SplitPersonality: Izumi plays a character with three personalities.
* SleepLearning: [[spoiler:Izumi got his acting talent due to his mother reading him her scripts as bedtime stories.]]
* {{Squee}}: Ryouma upon kissing Izumi while the latter is asleep does this internally.
** Izumi does the same after being greeted by Ryouma through text while in denial of his feelings for him. He proceeds to chastise himself for doing it.
* StrongFamilyResemblance: Shougo is basically the younger version of his dad while Izumi has Nagisa's looks which is evident when he is dressed as a woman. It also helps that the parent they resemble is also how their bangs are styled with Shougo's parting to the right like his father's and Izumi's are towards the left like his mother's. Shougo's resemblance to Seiya is also quite noted in the Back Stage novel.
* StealthInsult: Rei at one point states that Izumi has been making a lot of progress already for a "virgin otaku". Izumi proceeds to lampshade it.
-->'''Izumi:''' Did you just casually insult me just now?
* TerribleArtist: Despite wanting to be a mangaka, Izumi's drawing skills are…well, let's say that it sets the bar pretty low.
* TheirFirstTime: The last two episodes of the anime center around Izumi and Ryouma having sex for the first time. To prepare himself, Izumi even buys some BL manga to find out if it hurts to have sex with another man.
* {{Uke}}: Izumi and Rei. In the in-universe doujinshis pairing Ryouma and Shougo, Ryouma is the {{Uke}} of the pairing.
* UnrequitedLove: Ryouma has been in love with Izumi for ten years and is greatly saddened when he finds out Izumi is a boy, but his feelings remain, but aren't reciprocated. [[spoiler: Izumi slowly begins falling for Ryouma and eventually become a couple.]]
** It takes Rei ten years to fully reciprocate Shougo's feelings for him and move on from Seiya.
* UnsettlingGenderReveal: Ryouma was sure that Izumi was a girl. He...didn't take the revelation very well.
** Happens again during the debut conference. Izumi, while cross-dressing, reveals his gender ''in front of a crowd''. Needless to say, the press was in complete shock.
* WhatBeautifulEyes: All characters' eyes are drawn in a distinctive style, though Izumi's are the best example.
* WholesomeCrossdresser: Izumi, though never by choice.
** While recovering from the shock about Izumi being a girl, Ryouma accuses him of being a CreepyCrossdresser, instead.
* WrongGenreSavvy: For an otaku, Izumi can be pretty... idealistic when it comes to attempting the seme role in his and Ryouma's relationship. His BL research has him listing all known seme types, but he insists on being the super seme--which, as Rei later points out, is nowhere near possible for Izumi through physical requirements alone (though Izumi begs that a guy can dream). Izumi might have better luck as the shota seme.
* YaoiFangirls: Shougo's and Ryouma's fan girls; so much that [[spoiler: there are actually in-universe doujinshis pairing them together]]
* YouWouldntLikeMeWhenImAngry: Izumi mentions that Rei is very scary when he's angry, such as when Rei saved a 9-year-old Izumi from a man who tried to lure him away with candy. When the director of the manga tried to sexually harass Izumi again, Rei made him back off, and Izumi remarked that Rei was so scary that he looked like a Yakuza.
* {{Yakuza}}: Rei is apparently a former Yakuza, although he will deny it if asked.
* YamatoNadeshiko: What little is shown of Nagisa's career has her playing the role of this in a scene. [[GenkiGirl Though, she's not so much one in reality.]]
