Hoist by His Own Petard: Apollo's Evil Plan succeeds, but he thinks he has all 77 Relics, when there are actually 78 — the rumor of 77 was planted by the Guardians themselves, who knew there were 78. Having an incomplete collection, Apollo's 77 Relics proved to be too powerful for him, gruesomely destroying him as he tried to unleash their power.
Gambit Pileup: His plan and the Guardian's plan and the heroes plan etc.
Gambit Roulette: In between her needed times of Central Temple maintenance, she intentionally divides herself into smaller pieces and scatters them among the worlds as individually powerful Relics, to promote the raising of heroes who will be powerful enough to collect and assemble the Relics, and then assist her in carrying out repairs.
Genki Girl: She's quite chipper and good-humored, much to the party's surprise.
Faux Affably Evil: She thanks the main characters for defeating Ashura, and grants them permission to come and go in her megalopolis as they please. This is the only extent of her niceness, and she doesn't even to try to disguise how much of a depraved Alpha Bitch she is.
Beauty Is Bad: Olivia decides that freedom from the controlling Venus means marring her own beauty. She slices her own face with a knife and then requests Venus to banish her from her megalopolis. This only pisses Venus off.
Easily Forgiven: Julius isn't really one of the good guys or one of the bad guys. He seems rather ambivalent to Venus's control of his life, mostly excited about getting to marry someone like Olivia. When Venus is finally defeated and Julius is no longer betrothed to Olivia, Julius apologizes for his arrogance and remains friends with Olivia and Antony. Olivia points out that Julius didn't actually do anything bad — he didn't actually have a choice in the overall situation, so she saw no fault that needed to be forgiven.
Mr. Fanservice: Julius is said to be popular with the girls, though he himself doesn't seem to be fully aware of this.
Evil Is Sexy: Okay so he's not evil, but this is the trope that allows Imp/Devil monsters to remain inside the city. invoked
Hopeless Suitor: Julius actually genuinely likes Olivia, but has no real chance of winning her heart from Antony.
Horned Humanoid: A demon who's beautiful enough to live in Venus's megalopolis.
Beauty Is Never Tarnished: He only injured his leg, and was still quite beautiful. Venus did not agree, seeing the injury as something that tarnished Antony's perfection, and she banished him from her megalopolis.
Giant Space Flea from Nowhere: After you defeat Sh˘gun, ďgosho arrives out of nowhere, announcing himself as Sh˘gun's father, and then kills his own son for failing him. You have to defeat him then and there, and he's as difficult to battle as the other God battles. Sure enough, defeating him yields a cache of Relics.
Deal with the Devil: Earlier in the game, if your party is annihilated in battle, you will be transported to Valhalla, and Odin will offer you a Bargain with Heaven to be resurrected from the beginning of the battle, if you agree to fight Odin someday. But when you finally reach Valhalla through the Sky Pillar, you'll have to fight him anyway, regardless of whether you made the deal. It turns out he was just another Deity of Human Origin searching for more Relics to make himself powerful.
