Other mistake: The game mode facing enemies of growing difficulty with two different parties is called "Trials of Athena", but in parts of the game (such as the daily activity quest recap) it becomes "Trails of Athena."
Character mistake: The side story showing Aiolia trying to meet with the Grand Pope has a few minor mistakes (such as "I've need to meet with the GP", to Aphrodite).
Other mistake: One of the questions Kraken Isaac can pose to the player is "Who are the other two?" It is obviously missing the first part; other two what?
Character mistake: In sidequest 10.4 (the one where he has to restore the temple of Lybra) Carlos says "Let me see think whether there's a good way"
Character mistake: In the side-mission against Deathmask at mount Gohoro, the Sanctuary Executioner says at first that "the ones who came with me don't know", but suddenly it becomes a single person "I'll write him a note."
Character mistake: In the side story 10.2, a blind Shiryu has to face the golden Saint of Cancer as end boss to protect his master. In the dialogue before the fight, Shiryu says "I told you before, I won't allow you to lay a hand on Deathmask." But Deathmask is the name of his opponent, he should have said "I won't allow you to lay a hand on Master Dohko."
Character mistake: Before the second part of the duel with Shiryu at the end of Story Chapter 1, he mentions breaking Seiya's cloth, but it is the other way around.
Other mistake: During side-mission 10.1, the mythical botanical part used to bring Hyoga back from the dead goes from being a pistil, to a stamen - it could be object of debate which one is the right version, and if there's enough difference, but what surely is wrong is when the "Sacred Stamen" becomes for step 5 of the quest a "SCARED Stamen."
Other mistake: In chapter 10.1, "Relieving Hyoga Crisis", one of the steps requires answering a quiz. Question; "Who guides souls to Acheron?" Possible answers; Bailishouyue, The Hulk, Alladin, Sirens. Right answer? Sirens. Which it's not, and the next line of dialogue in fact says; "Hermes, yes, that's the name."
Other mistake: In Ichi's self-training mission, he fetches a single rose, but the icon used is the one of a bunch of roses, and also the description in that screen says 'roses' in contrast with the singular before and after.
Other mistake: When you receive in-world mail notification about a new Saint's friendship level increase and part of their profile unlocking as a result, the game does not have a distinction between female and male characters. Therefore you get mails such as "As your friendship has grown with Saint Marin, he is willing to tell you his life story." Marin is a woman.
Other mistake: In the encyclopedia of the game, training ground section, the entry about Andromeda Island has somehow the wrong title; a trivia question. So the paragraph describing the island has as title; "Who did Pegasus Seiya first use the Pegasus Meteor Fist against?", which is entirely unrelated (not anyone who was on the island or shares any history with it).
Other mistake: If you choose to exit a dungeon while in group, the "Plot redirect" dialogue box asks you for confirmation if you want to move when you are "Currently in an dungeon."
Bug: In the quest to "Find Kiki the troublemaker" you have to find Kiki in a random location in the Townlet. In case you answer the trivia question wrongly, the dialogue says that you have to find him again. But Kiki does not respawn anywhere else, so you can simply click on him again, as he is still standing in front of you.
Other mistake: The intro of the sidequest 7-1 "Lost in a Horoscope" says that Marin returns to the Sanctuary "with full of doubts."
Character mistake: With Saori unconscious outside, Jamien ponders why can't they just kill all of those "Saints who fights each other."
Character mistake: Mu's speech repairing the armors in the Aries temple recites that "It is not the Cloth that determine the strenght of a Saint, but the extend of their Cosmo." Should be 'determines', and 'extent', or 'extension'.
Character mistake: In the explorer quest with Julian and his cronies, Ryan says after one of the preliminary fights with the "endangered species", that "we will explorer [sic] in the depths." In the same quest, after another battle Kanon warns that "we won't won't be getting much sleep", in a repetition.
