Light Novel: Dakara Boku wa, H ga Dekinai. aka: So I Cant Play H
High schooler Ryosuke Kaga is also known as Erosuke for his extreme adolescent interest in the erotic side of life. One day he encounters a young girl standing alone in the rain. She is Lisara Restor, an elite Death God who has come to Earth in search of a human known as the "Singular Man."Ryosuke ends up making a contract with Lisara, allowing her to suck the energy she needs for her activities on Earth from him. And it turns out the source of that energy is his own perverted spirit! As a result Ryosuke can no longer feel aroused in the heat of the moment. After trying every erotic method he can think of, he finds he has no choice but to help Lisara in her search in order to recover his perverted spirit.”Not to be confused with High School D×D, which started airing an anime around the same time with a similar red-haired Magical Girlfriend.US viewers may watch this legally at Crunchyroll or Hulu, under the title So, I Can't Play H?, albeit heavily censored.
Ilia herself after it's revealed that her boobs are fake and she's smaller than Lisara
Art Shift: Episode 10's backgrounds have a much different tone than the previous ones. Largely because the gate between Earth has been severed, and reapers are killing off people that should have died a long time ago before the Restall family took pity on humans and allowed them to live longer.
Censor Steam: Done pretty poorly, usually a solid black or white line stretching across and blocking much of the screen, to the point where it can be distracting on its own. Worst in the fight scenes, where copious Clothing Damage means most of the scene is covered by a giant black bar half the time. Doesn't apply to the uncensored versions.
Clingy Jealous Girl: Lisara when Ilia begins flirting with Ryousuke in episode 4. She also gives him a dirty look when Ilia shows up at their house in episode 6, and also when his mom asks which girl he's dating.
Corner of Woe: After Ilia and Quele try to one up each other while on a video chat with Ryousuke's mother, Lisara boasts that he's seen more than just her breasts, prompting a long, awkward silence and stare from all of the other characters. In the next scene, Lisara is sitting far away from the group covered by a blue aura of shame.
Date Peepers: Lisara, Ilia, and Quele do this in episode 11.
Defeat Means Friendship: Quele and Ilia are much less hostile towards Lisara after she beats them. Of course, she doesn't like the two girls chasing after Ryousuke either.
Despair Event Horizon: After Dalnia shows Ryousuke what's happened in the week between episodes 9 and 10, he loses his will to live, citing that its unfair that he should get his life extended while lots of other people who should have expired a while back are dying.
Mina herself does this at the end of episode 12, after seeing an explosion come from Ryousuke's house. She says if Lisara still treats him like dirt, she'll claim Ryou-chan for herself. To which Quele mentions that she's got a dark side, causing Mina to panic and invoke this trope.
Disappeared Dad: Ryousuke's father is dead when the show starts. But then his mom reveals that he's actually still alive, but went somewhere and left them alone. She figured it was easier to tell him that he's dead rather than just gone from his life.
Becomes a plot point again in episode 6, when Ilia asks Lisara why she's trying so hard to find a replacement for him. She plans to find the person with the most power and have them help save Ryousuke.
First Girl Wins: If the opening and ending credits weren't obvious enough about it.
Heroic BSOD: Ryousuke suffers one in episode 7 after failing to protect Quele during a fight with a large number of monsters.
Heroic Resolve: In episode 8, after learning that Lisara purposely left Ryousuke behind to rest and prevent Gardarblog from taking Gram from him, he decides to head towards Gardarblog's tower to save her and Mina. As he says this, he manages to pull out Gram again.
Heroic Second Wind: After suffering a powerful blow from Gardarblog, Ryousuke regains some of his composure/energy after touching Lisara's arm, and telling Gardarblog that women's upper arms are just as soft as their boobs. Cue confused look from Gardarblog.
Hopeless Suitor: Pretty much any girl besides Lisara. Doesn't stop them from trying however.
Hot-Blooded: This trope is in play during episode 7 when Ryousuke's strategy for rescuing Mina was to charge the enemy stronghold head on, which is exactly what the bad guys wanted him to do. He refuses to listen to Lisara's advice which was to gather intelligence and build up their strength first.
I Have You Now, My Pretty: Gardarblog kidnaps Mina at the end of episode 6, and taunts Ryousuke and Lisara to come after him if they want her back.
Imagine Spot: Quele has one in episode 6 of Ryousuke and Lisara doing naughty things. She then says she has to win his heart before that happens.
Informed Ability: Despite Lisara supposedly being first in her Shinigami class and doing a supposedly good job exorcising spirits, she for some reason cannot go a single fight (or episode for that matter) without relying on Ryousuke charging her up. She also tends to have a lot of Leeroy Jenkins moments too, blindly charging in when it would have been better to be on the defensive.
Intimate Healing: Two of Lisara's maids in episode 7 lick his wounds to heal them. Lisara doesn't seem too comfortable with it. Quele attempts to do this as well in episode 8.
I Want My Beloved to Be Happy: Lisara's motivation for getting Mina and Ryousuke together. Turns out that Mina was the person the grim reapers were searching for in the beginning who had the immense energy. It was first detected with Mina's botched Love Confession to him a while back, and then she activated it again as she was falling to her death in episode 8, only to have the energy save her. Lisara figures that the energy from Mina could be used to extend his life, but every time she mentions it, she has a sad look on her face.
Love at First Punch: Ryousuke tells Lisara at the end of episode 11 that despite her beating him up when they first meet, and being a Tsundere towards him, he gradually fell in love with her anyway due to how dedicated she seemed to be in her mission to find the person with the massive energy readings they detected earlier.
Love Confession: Mina gives one to Ryousuke in a flasback in episode 7, but because she worded it a bit weird ("I want you to protect only me now"), and because Ryousuke's probably Oblivious to Love, he took it to mean something entirely different.
She gives him one again in episode 11. It was in an attempt to save his life by absorbing some of the massive energy emanating from her. Then he blows it by not accepting her feelings.
Then after Lisara berates him for rejecting Mina's love, he gives her one, which only hurts her more as she knew he was dying and couldn't save him without Mina.
Lisara gives him one in episode 12 while saving him from entering the afterworld, which helps convince him to come back despite being resigned to his fate earlier.
Love Epiphany: Quele seems to undergo this in episode 5. Lisara seems to have one in episode 6, after Ryousuke reveals that despite the danger to his health, he's doing all he can to help protect her.
Love Hurts: Although subtle, in episode 9, Mina seems unhappy when she sees Ryousuke coming to rescue her and Lisara, but seems much more focused on Lisara.
Lisara in episode 11 while watching him and Mina on a date. She doesn't seem very happy watching it, then leaves about halfway through the date.
Lured Into a Trap: Lisara in episode 8, after Ilia is ordered to bring her to the tower and lure her into a room where they could capture her.
Mind Screw: How the worlds affect one another, according to Garudabloug in episode 9. To sum up, If the humans' lives are extended beyond their predicted lifespan, it causes energy crisis in the other world. Which, in turn, somehow (?) makes humans go to war and experience famine.
Most likely he meant that overpopulation due to people not dying when they should be, would lead to food shortages, since there can only be so much food grown, and people have gone to war for much less stuff. So if the population were kept in relative check, then the humans wouldn't upset the balance so much, and war could likely be averted. Hence Gardarblog's sort of reasoning behind what he was trying to do.
Mood Dissonance: At the end of episode 11, Mina and Ryousuke's mother are both crying as he's laying in his bed, having died just moments earlier, with some sad music playing in the background. Then the closing credits kick in with its very cheerful music...
Lisara's mother has a similar gradient effect, just with red as the 'normal' base.
Naked Apron: Both Lisara and Quele, with a bikini under. Ryousuke isn't any less pleased when he finds that out.
New Transfer Student: Lisara does this in episode 2 in order to find a person with immense energy potential. She does it under the guise of being a distant relative of his. Followed by Quele in the next episode and Ilia in the episode after that.
Nice Job Breaking It, Hero: Happened during episode 9. To summarize, Ryousuke pinned Garudabloug to the device that apparently mainains the existance of the barrier between the worlds, and Lisara's World's artificial sun.
Nose Bleed: Played with in episode 1. Ryousuke suffers from one after trying to look at Lisara's panties, only to find out she's not wearing anything under her dress. He then suffers one, but it's likely because she also swung her foot down on his face right after he says she doesn't have anything down there.
Not So Different: When Ryousuke's mother is relating to him how she met his father, it happens the exact way he met Lisara in episode 1. Except that it ended in the two making love, which grosses him out.
Obstructive Bureaucrat: Dalnia in the later episodes. Everything she does is simply for the sake of business, although to the other characters she appears to be a heartless bastard in doing so, such as when she was attempting to collect Ryousuke's energy after he died at the beginning of episode 12. Despite the other character's pleas to wait, she tries to harvest it right away.
The Power of Love: Turns out that this causes humans to create even more energy, which Dalnia exploits at the end of episode 12 and called this "Life Jewel", so that the reapers can help humans obtain happiness, so that when their time does finally come, they'll be able to harvest more energy than if they did it the old way of just harvesting humans as they die. This also means that Ryousuke won't have to feel guilty about living longer anymore.
Reality Ensues: When Ryousuke attempts to do the cliched Leeroy Jenkins move virtually every single action/Shonen hero does when saving someone they care about, he ends up fucking up badly, nearly costing both his and Cule's life and ends with him having to get saved by Lisara. The next episode has him even deal with a bout of PTSD, a highly unusual and extremely rare thing to happen to the standard Shonen hero.
Scars Are Forever: The scars Lisara obtains in the later episodes remain on her until Ryousuke starts absorbing it as he was about to head into the afterlife.
Screw the Rules, I'm Doing What's Right: Ilia, after thinking about Lisara's predicament, as well as the trust Lisara had in her, decides to save her instead of letting her be captured and tortured by Gardarblog in episode 8.
Stealth Hi/Bye: Ilia does this in episode 6, showing up inside Ryousuke's house.
Strip Poker: They play this in episode 10, to prevent Ryosuke from finding out the truth about the situation. It ends with all girls in just their underwear, and Ryosuke gets a Royal Straight Flush. Then they find out he was cheating.
Take a Third Option: In episode 12, Dalnia, having witnessed Ryousuke being brought back to life, and the immense amount of energy this "regular guy" was emanating upon being reunited with Lisara, decides to instead help humans to obtain happiness, as she sees that they can collect more energy this way rather than simply killing them off to absorb it during their death.
Taking the Bullet: Quele gets hurt by putting herself between Ryousuke and an attacking monster.
Thanks For The Mammaries: Ryousuke does this to break up a fight between Lisara and Quele in episode 2, by grabbing both women by their boobs.
The Only One Allowed to Defeat You: Ilia gets upset that her company Merlot would send a creature on their own to try and defeat Lisara, when she vows to be the one who does it.
She saves Lisara again in episode 8, vowing that she would be the only one to defeat Lisara, and saving her from the trap set up by Gardarblog.
The Reveal: In episode 6, Ryousuke's mom tells him about his father, who left the other half of the sword in him, which is why he was able to reforge it in the previous episode. She also tells him that his father isn't really dead, but just left somewhere to fight. She just told him he died to make it more convenient. She also gave him the name "Ryousuke", as he couldn't remember what his was, and she needed something to call him by, hence why their son has the same name.
Too Kinky to Torture: Lisara's physical abuse to Ryousuke only seems to turn him on more, which freaks her out when she's stepping on him in episode 1.
Tsundere: Lisara. In episode 10 she even said, "Don't get the wrong idea!"
Undead Tax Exemption: How Lisara, Ilia, and Quele all manage to hang around Ryousuke as well as attend his school without anyone getting too suspicious.
Unlucky Childhood Friend: Mina seems to be falling into this trope. He outright rejects her when she asks again in episode 11. Then in episode 12, she finally reads a text message he sent her, and says that if they weren't such close friends already, he would have been happy with her.
Villain Ball: According to what he said in episode 9, Gardarblog probably could have saved himself a lot of headaches and his life, had he told Ryousuke right away what he was trying to do, and not threatened Ryousuke's friends in the process. Ryousuke may not have changed his mind, but at least he could see that Gardarblog wasn't just a trying to be a bad guy who was simply trying to do stuff For the Evulz.
Well-Intentioned Extremist: Gardarblog's rationale for what he does. In episode 9, he tells Ryousuke about how they used to cull human lives at a regular interval, until the families such as Lisara's took pity on them, and allowed them to live much longer than they normally should be able to. He wanted to get Grimwald so that he could resume doing his job of culling humans to prevent them from overpopulating and causing even more destruction and mayhem through war for food/supply shortages.
