Angelic Beauty: All the angels look like either pretty girls in maid outfits or handsome men in butler outfits.
Animated Actors: This is essentially what Cinderella and the Prince are, engaging in banter in between scenes or when their story isn't told.
Ascended Demon/Fallen Angel: Angels can become demons and vice versa. Amongst the cast, Cheriel is an Ascended Demon while Varael is a Fallen Angel. In fact, the Creator only created Black Wings (demons) and the reason why White Wings (angels) exist is because some Black Wings gave birth to White Wings while other Black Wings chose to transform into White Wings.
Bad Future: The setting of the Lesson 7's wish is in a future where Renya is killed by Varael, Liliel is killed by Frunetti shortly after, some of the strongest bases in Celestia are destroyed by Satanael, and Minamo becomes the next target of Varael and Frunetti.
Battle Couple: Renya and Liliel grow to become this over the course of the story.
Breakable Weapons: Subverted. Unlike in Zettai Hero Project, your equipment has a "Burst" meter. While reaching 100% burst DOES reduce the item's effectiveness, every time you do so you get a panel that you can use to upgrade you stats, and if you bring it outside of the dungeon you can upgrade them to more powerful forms with the blacksmith.
Clothes Make The God: Renya and the other angels can equip a variety of clothes, armor, and weapons which bestow upon them stats and new abilities.
Did You Just Punch Out Cthulhu?: The entire game is pretty much about making Renya, an ordinary human, powerful enough to take on Satanael, the game's closest thing to...well, Satan. Renya also gives the Creator, the closest thing to an actual god, one big punch to the face. The Creator even says it hurt more than he expected it to.
On top of that, the Martial Dungeons gives Renya quite a few divine figures to punch out. These include Buddha, Hades, Zeus, and Prince Yamato.
Mysiel's wish in Lesson 8 is for someone to get a slap in the face, but she doesn't specify who. That person turns out to be Galtion for trying so hard to see her again. In the end, it's Neliel who delivers the slap.
Rakiel loved a woman who previously was God but was consumed when she failed her duties.
Galtion loved Mysiel, who sacrificed her life to complete the Fate Revolution Circuit.
Mayfly-December Romance: 17-year-old former-human Renya and 1,609-year-old angel Lilliel, in the ending. Hopefully Renya still has that immortality in effect.
Multiple Endings: Surprisingly averted. Guided Fate Paradox is one of the few Nippon Ichi games to lack any alternate endings whatsoever.
Mind Screw: Neliel has warned Renya that the entire chapter 6 was going to be one. She wasn't kidding. For starters, the wish belongs to Minamo one year later in the future, her Renya has been dead since then, and Minamo is a sorceress and made a deal with the devil.
Our Angels Are Different/Our Demons Are Different: Well, both are very nicely dressed. And it turns out that the only difference between Angels and Demons are the names they call themselves and the color of their wings. The Creator created the "Black Wings" (demons), but some Black Wings gave birth to "White Wings" (angels) and others were able to change of the color of their wings.
Peninsula Of Powerleveling: At least, in terms of money, bursting equipment, and future leveling. Chapter 8 boss has you fighting against Mysiel's clones who respawn every time the floor moves. With a Paw Paw weapon, use the "Lucky Lure" skillnote Assures a money drop from a defeated enemy for a few turns and keep on one-hit killing the infinitely spawning boss. This trick disappears if you finish the chapter.
Any floor with zombies can yield a lot of EXP as they never truly disappear like other enemies unless killed with certain weapons. With the right setup, you can simply stand around and watch as Renya and his partner rakes in EXP, zombie gear, burst equipment, and money.
Sharp-Dressed Man: Seems to be a requirement whether you're on the side of the angels or the devils, even the beastly ones like Varael.
Second Love: Thanks to Renya's efforts, Galtion realizes that he shouldn't be chasing after Mysiel's shadow, and hooks up with Neliel.
Sesquipedalian Smith: Most of the angels' first names follow traditional angelic theme naming, but their last names are Japanese. Renya even lampshades it, wondering how angels have last names, and Japanese ones at that.
In Lesson 1, Renya punches the Prince for not responding at all to Cinderella when the magic fades after midnight and gives him an earful.
Calling My Sister Out: Eleanor in Lesson 3 calls out her sister Thelma for being so unable to get over her break-up with her lover and trying to take it out on the entire human male population.
After completing Minamo's wish, Renya calls out the angels for dragging humans into their war, all of whom died before Renya was chosen. After this, Renya chooses to continue his duties only so that he can return to his normal life and is bitter towards most of the angels except Liliel and Kuroiel.
Renya calls out the Young Man's irresponsibility with his power of creation, especially the creation of Satanael. At the end of Lesson 7, Renya even punches him.
Zettai Ryouiki: Lilliel, Kuroiel, and Neliel are Grade A while Cheriel is a Grade B.
