Kiba, sometimes you say nice things for a damn pretty boy! Note
Despite the fact that the series is a harem series, somehow the author was able to sneak in a few of these. Hey, Issei's wish is to become a Harem King and no one ever said harems only needed to be from the opposite gender.
- Kiba is sometimes this to Issei like the time when he was really grateful to Issei for resolving his dark past, he comments that It's hot around my chest region. Issei just finds him disgusting when he's like that, it didn't help Kiba is too serious about it to be passed as teasings or jokes. At least in Issei's head, Kiba doesn't seem like joking at all.
- Kiba and Issei is Lampshaded by nearly everyone including even the author. It doesn't help that Kiba thus far hasn't shown any interest in anybody yet except his moments with Issei. He starts joining the girls in their activity to score points with Issei, ranging from cooking food to wearing a nurse outfit after changing genders.
- The author eventually out and out calls Kiba a heroine in the afterword of Volume 12.
- In the Volume 13 short story "The Disturbance of a Devil", Kiba decides to use one of Azazel's inventions to reverse his gender and turn himself into a bishoujo just to help Issei get better after he falls sick. He even wears a nurse's outfit. To top it off, he's not used to wearing heels so he accidentally trips and falls on Issei and starts to blush. He starts to confess something to Issei but we never find out what because the girls walk in on them. Hilarity Ensues.
- Just to give an example: after Issei's Training from Hell with Tanninim, Kiba sees Issei's new body and just utters "Nice body." This makes Issei blush and cover himself up.
- And then in Volume 14, it's shown that Kiba has refused the invitation from the girls that had invited him to eat with Issei with food he personally prepared for the both of them.
- Now we head into the first chapter of Volume 18 where ORC are preparing for their devil jobs during Christmas time. Issei correctly guesses that Kiba will get increased requests from older women. Kiba declines, though, and promptly reveals he is planning to bake a cake and wants Issei to eat it. Cue Kiba making, in Issei's words, 'the eyes of a maiden'. Issei quickly evades the encounter by texting Shinra about it and asking her if she'd like a slice of Kiba's cake.
- Then there's the short story The Student Council's Decision where a popular doujinshi is being published with Issei at the top and Kiba at the bottom. When the student council and Issei (long story) find out about it, the entire manga is in its fifteenth volume.
- Story about the style of Miyama Zero (Crossover with The Ambition of Oda Nobuna): Upon performing the aforementioned style, Issei and the ORC have swapped places with Nobuna Oda and her retainers. Kiba becomes extra motivated to bring them back after blushing at the possibility of Issei using a feminization technique on him, just so he can learn the technique.
- Kiba and Issei is Lampshaded by nearly everyone including even the author. It doesn't help that Kiba thus far hasn't shown any interest in anybody yet except his moments with Issei. He starts joining the girls in their activity to score points with Issei, ranging from cooking food to wearing a nurse outfit after changing genders.
- Gasper is just as bad, if not even worse. He's nearly as dependent on Issei as Asia is.
- In the first short story of Volume 13, there's a scene where Issei gives him blood from a wound on his finger. He notes how warm it is in Gasper's mouth and how dangerous his thoughts are starting to get. What's more, his subsequent power-up and fight are all for Issei.
- To say Gasper became attached to him would be an understatement to the point where he says this after seeing Issei, who was sick at the time, and Kiba, who turned himself temporarily into a girl to cheer Issei up per Azazel's suggestion, holding each other after Kiba trips and Issei catches him:"I…I should also become a girl to do things with Senpai…."
- And then there's Volume 14 where he now also wants to sit at Issei's lap.
- That isn't just a wish, he actually does it whenever Koneko and Ravel aren't around.
- There's also the fact that he woke up to his power when he heard that Issei died.
- On the Les Yay side, we have both Xenovia and Asia, who despite the fact that both love Issei, Xenovia's pretty touchy with Asia like the one time they were at the gym locker room, she undresses Asia personally.
- Xenovia, in general, tries to include Asia in everything she does with Issei and goes absolutely nuts when Asia is hurt in any way.
- Serafall is very open about her incestuous desires for her sister. For her part, Sona's embarrassed reactions are entirely regarding Serafall's public clinginess; she shows no revulsion regarding the incestuous attraction itself.
- Rias and Akeno get in on it during the onsen scene, where Akeno was apparently doing something extremely arousing to Rias' breasts. To the point, Rias told Akeno to stop because she wanted Issei to be the first to do that to her.
- Rias' first meeting with Akeno is to compliment her black hair back when they were kids. Sure Rias is an Occidental Otaku, but...
- And there's the fact that Rias' Queen is Akeno.
- When Koneko was under a spell that Rias put where it was meant for Issei to reverse his personality which made Koneko a pervert and strip both Rias and Asia and play with their breasts. Under the shower no less.
- There's a one-sided relationship between Issei and Vali.
- Not only Vali but Sairaorg and Cao-Cao of all people have the Blood Knight version of a man-crush on him, seeing him as a worthy target to defeat.
- Sairaorg has been sending Issei gifts as of Volume 14, a behavior most likely influenced by Issei being a rival for him, being good friends, and even having resolved his emotional baggage when Issei used Bilingual on Sairaorg's mom and eventually causing her to wake from her coma.
- It's worth noting that Sairaorg is deeply involved in the Devil court system, and the last Devil so who started sending gifts to someone had expressly romantic intentionsnote . Sairaorg is openly expressing Courtly Love towards Issei.
- And then there's Saji and Issei. Saji's powers work right only if Issei is with him because of the dragons that are within them. And then when Issei finally died, Saji cried a lot and swore that he would take down Khaos Brigade or die trying.
- Then there's Xenovia and Irina. Especially Volume 14 where while all the girls were sleeping at Issei's bed, Irina uses Xenovia as a hug-pillow. Hell, these two alone could fill up an entire entry but some other early examples include:
- After Xenovia becomes a devil, Irina looked like she and Xenovia had a bad breakup.
- Both girls are almost inseparable to the point you'd think they were a couple by themselves.
- Basically, the pair have a very Pseudo-Romantic Friendship going on, to the point where one wonders if Irina's enforced chastity is only frustrating Issei.
- Sirzechs and Ajuka have been going at it for quite a long time. Ajuka will only do something if Sirzechs asks him to do it. Despite being equals, Ajuka will always defer to Sirzechs' judgment no matter what. Threaten Sirzechs and his plans and he will give you one hell of a thrashing.
