The Protagonist. Formerly an Ordinary High-School Student (besides a stint at a junior high baseball team that ended with a Game-Breaking Injury), he became caught up in the world of magic and gods when he unintentionally became the seventh and latest Campione, as well as the youngest at age sixteen. He now struggles to maintain his ordinary life while being surrounded by scheming magicians, belligerent gods, and the various girls vying for his attention.
The Ace: He'd never admit it but he was one of the best baseball players before the start of the series and in fact had been chosen to represent Japan before his injury.
Badass Unintentional: How he became the seventh (and youngest) Campione in the first place. He was just trying to stop a fight!
Berserk Button: Don't hurt girls, threaten girls, much less make a vaguely hostile motion towards them within his reach. Just don't.
The Bet: He made a bet with Liliana that Hikari, Yuri's younger sister, will not fall in love with him. As expected, he lost.
The Casanova: He becomes this in Youth Form. The normally dominant Erica notes she can't really deal with him in this state.
Celibate Hero: Unique case. He is very happy to receive Erica's affection such as when she ask him to travel with her during the summer but there was a catch. He definitely could not agree with her wishes as promptly as this. If he did, it would end up being a progression of travel—wedding—pregnancy—child-rearing, and by the latter half of his twenties, the majority of his (natural human life span) life would be semi-automatically decided just like that—something as scary as that could happen. Thus, Godou felt that he must never ever lower his guard and resist with all his might when he is around her.
Godou: Even if it was just a verbal marriage proposal, from that moment onwards, my life would have been deemed a called gamenote In baseball, a called game is one in which, for any reason, the umpire in chief terminates play. In other words, end game.! Even a playoff would be impossible.
Clueless Chick Magnet: Just to drive the point home, he attracts the attention of two Campiones (as a Cool Big Sis for Luo Hao and John Pluto Smith aka Annie Charlton who berates herself that she got attracted to a kid ten years younger than her.) Later Madam Aisha, the last Campione to be introduced, joins the list.
Combat Pragmatist: Although he claims not to enjoy fighting, when he does fight, he does so to win. While he doesn't fight outright dirty, he's not above doing such tricks as fooling his enemies into charging up their most powerful attack, then subduing them before they can use it.
Combined Energy Attack: Verethragna's ninth incarnation, the Goat, grants Godou the ability to manipulate lightning. Its power is fueled by his allies' will, but also their Life Energy, willing or otherwise, something he learned to his great distress after being told that his use of this ability for the first time caused everyone within a kilometer of Tokyo Tower to fall unconscious.
Cool Sword: Sword of the Beginning and the End. He can use this to create a sort of black hole which he used to annihilate an entire island.
Required Secondary Powers: Defeating Circe didn't grant him a full Authority because of her weakened state but what it did grant him was the aspect of a witch that allows him to manifest the Sword of Beginning and the End without having to rely on Yuri or Lilliana's assistance.
Dangerous Forbidden Technique: Some of his powers can hurt or cripple him after use. Specifically, the Raptor leaves him with intense heart strain, the Goat sucks up the life force of others, and the Ram kills him before bringing him back.
Deadpan Snarker: This is how he interacts with Erica because her clinging and manipulation irritate him.
Destructive Savior: If there's anything of historical significance in the vicinity of one of his battles, chances are that it will end up as collateral damage. Often causes him some distress upon realizing just how much destruction he's accidentally brought about.
Does Not Know His Own Strength: One of the reasons why he didn't play Baseball after his Game-Breaking Injury healed is that he didn't want to accidentally use his super power during the game. Also played straight in vol 8 during time when he tried to cast a spell to break matchsticks, except he broke a tree instead of the target matchsticks.
Fatal Flaw: Refusing knowledge about his enemy, which is the condition for use of the Golden Sword, because it involves oral contact. Given the Japanese view on intimacy, this could be understandable, but when he's fighting individuals who are out for his blood, and that he can only resurrect once a day, it borders into Idiot Ball territory at times.
I Just Want to Be Normal: Too bad for him, fate seems to interfere every single time. A Campione cannot live a quiet life.
Indy Ploy: Godou rarely plans too many steps ahead in a battle, often improvising to adapt to shifting circumstances. It is all but stated in the novels that his ability to to make split-second judgments to secure victory is one of reasons he became a Campione in the first place.
Necessary Drawback: His "Persian Warlord" Authority effectively grants him ten powers for the price of one, but he can only use each one once per day and only after certain conditions have been met.
Nice Guy: It's regularly stated that he's 'not like other campione' because he'd rather be friends with people than fight gods or lord over mortals.
Liliana: To have so many girls distressed over you, and yet you remain completely unaware... You were born with a lady-killer's disposition. I, Liliana Kranjcar am impressed from the bottom of my heart. Kusanagi Godou, you are like a sleepwalking serial murderer, a rare and unaware lady-killer!
Superpower Lottery: On top of the fact that he has the 10 Commandments of Verethragna, one of those commandments, the Golden Sword, allows him to literally talk gods to death.
An Italian magician who was with Godou when he became a Campione. She fell in love with him, and decided to help him become a great king... whether he wants to or not. Though manipulative at times, she truly loves Godou, and ultimately everything she does is for his sake.
The Ace: She is a great swordswoman, and excellent magician, and can talk her way into and out of almost any situation with her eyes closed.
Berserk Button: Don't hurt Godou, or attempt to separate her from him. She won't take it well.
Character Development: As seen in Volume 3 of the light novels and Episode 1 of the anime, she started out as a Type A Tsundere. By the events of Volume 1 and Episode 2, she has fully made the transition to Type B, thus setting a record for one of the quickest Tsundere cycles in history. A Justified Trope; in the intervening time, Godou saves her from a fall of about five stories, saves her again from divine lightning, demonstrates courage and tactical intelligence, defeats a god, becomes a king, and stops a divine brawl that was about to destroy her home island. These are all pretty good reasons to stop treating someone like crap.
Cool Sword/Morph Weapon: Cuore di Leone. It can cut gods, turn into a lion, multiply, and even fight on its own.
Femme Fatale: A rare example that gets to be the main Love Interest. More sympathetic than the average example, since while she does try to seduce and manipulate Godou, she truly loves him and ultimately everything she does is for his sake.
Godiva Hair: One instance of her waking up naked has her hair covering her chest.
Guile Heroine: She's more likely to win by cleverness than by force because she's a mortal magician against gods and campione.
Harem Seeker: Initially by pressuring both Godou and Yuri into a relationship, because she thinks the latter's abilities would be useful. Averted when Ena appears, because unlike Liliiana and Yuri, Ena is beyond her control. She also starts to regret her actions later on as Yuri and Liliana start to break her influence.
"If you're thinking of continuing to bully my Godou, can I please ask you to stop? The only person that can love him, torment him, or treat him like a toy, is me, the Diavolo Rosso. That is a right given only to me, he isn't someone who you can play around with when you feel like it, you know?"
Lady in Red: Frequently wears a red dress and she is the most flirtatious of the heroines.
Rich in Dollars, Poor in Sense: She's well-informed in most situations, but mostly clueless about Japanese culture. An example of this is when she takes Godou to an area filled with love hotels, and has no idea what they are.
A Hime-Miko who has had past experiences with Campione; bad ones. She gets involved with Godou when he accidentally lures Athena to Japan. She begins to develop feelings for him that solidify once he saves her from the Campione who hurt her in the past.
Blessed with Suck: Her Spirit Vision is an inborn talent which gives her a chance of automatically acquiring information about any magical entities or phenomena she encounters. In a world where even the best practitioners can usually only activate it 10% of the time, Yuri can easily activate it over 60% of the time. However, this gift is the reason Voban kidnapped her four years prior to the start of the story.
Waif Prophet: Is by far the weakest character in the group in terms of fighting ability, but still gets to contribute using her Spirit Vision. Then she takes a level in Badass and tanks a goddess's chain of attacks with her own ability.
Yamato Nadeshiko: A Japanese priestess and excellent cook who's also the head of the Tea Ceremony Club.
A Hungarian knight and childhood friend of Erica. Originally working for Voban, she was convinced to switch sides. She becomes an official part of the group after Godou helps her defeat Perseus. She writes erotic love novels, which Erica uses to blackmail her.
Brainwashed and Crazy: Briefly due to Perseus' spell, which lets him control any woman with a mage bloodline to do his bidding.
Covert Pervert: If the embarrassing novels she writes are anything to go by, she has a dirty mind.
Cry Cute: After Godou wakes from a near-fatal encounter with Perseus, at the end of a bad day culminating with Godou discovering her embarrassing erotic novels, and when Athena beats her to giving him a healing kiss after the battle with Perseus.
Enemy Scan: She possesses the same Spirit Vision powers as Yuri has, albeit orders of magnitude weaker unless she receives assistance from a deity, as she did from Athena in Volume 4.
Lady of War: Unlike Erica, she spares the jokes and posturing for a composed and refined fighting style.
Made a Slave: She had once been Duke Voban's slave four years ago (Anime only). In the present, she became his slave in all but name when her grandfather ordered her to work for Voban, until the others convince her to defect.
Magic Music: Il Maestro is capable of using songs to influence enemies.
Subordinate Excuse: Insists that she only wants to serve Godou as his knight and is not in love with him. Somehow, in addition to protecting him, her duties involve preparing his meals, cleaning, mending his clothes and keeping other women away from him.
The Comically Serious: Her comedy is derived from how serious she tries to be when in embarrassing situations.
Vitriolic Best Buds: With Erica. The vitriol is entirely from her side, since Erica is firmly in control in their relationship.
A later addition to Godou's True Companions/Unwanted Harem, Ena is another Hime-Miko, though this time a more active combatant, wielding Ame no Murakumo no Tsurugi, an enchanted katana/tsurugi which temporarily grants her demigod-like abilities.
Badass: Deserves special mention for being stronger than Erica and Liliana combined! until they get their ...special spells working) The Ame no Murakumo essentially puts her outside the human realm and into that of a divine beast.
A Greek deity. Though named after the goddess of strategic warfare, she's actually a lesser snake deity associated with Medusa, a chthonic goddess of death. She seeks the Gorgoneion to return to her true form.
Badass: Even for a god. Both Verethragna (and by extension Godou) and Lancelot are Steel, who should have a huge advantage against a mother earth goddess like her. If it weren't for the Holy Grail she'd have killed them both.
Depraved Bisexual: She develops feelings for Godou, and strips and molests Liliana at one point.
Narnia Time: She can spend two years in the past and return two days after she left or spend an few months and return thirty years later than when she left. She actually has some control over this and will skip ahead to make it so she looks younger than her actual age... despite being an immortal Campione who age extremely slowly.
An Ice Person: If she doesn't watch out, she can cause an ice age. She's not the careful type to begin with.
Nice Girl: To an even greater extent than Godou, making her the nicest of all the Campiones. She prefers to use her authorities to help people rather than fight.
Power Incontinence: She has limited ability to control her Fairy's Corridor Authority. Deliberately attempting to activate it rarely works and Aisha cannot control the initial location, though she retains some control over the return journey.
Vague Age: Was born at least one hundred and fifty years ago but the nature of Fairy's Corridor the exact amount of time she has lived is ambiguous. She claims to be seventeen but Godou doesn't believe her.
Adventurer Archaeologist/Phantom Thief: His father had an obsessive goal to find the Holy Grail, when he died Alec took up his journey, it was during this time when he slew the Fallen Angel Ramiel. He later picks up the habit of just taking anything he deems interesting, sometimes leaving a note.
Badass Bookworm: He knows a lot about Japanese Mythology, and presumably others too.
The Italian Campione and Europe's finest swordsman. He fought Godou in the past and has regarded him as a Worthy Opponent ever since. He's killed at least four Heretic Gods, Nuadha, Siegfried, Vulcan and an unknown fourth God. In Volume 4, he delivers the finishing blow to Perseus, but he did not gain any Authorities from it.
Crouching Moron, Hidden Badass: At a first glance he seems like your average Cloud Cuckoo Lander, missing important meetings to eat ice cream and regularly forgetting people's names. In truth, he simply doesn't pay attention to or bother remembering things he isn't interested in. Catch his eye, however, and he becomes frighteningly focused and competent, as Godou found out to his dismay.
Nigh-Invulnerability: Granted by his "Man of Steel" Authority, although the invulnerability granted is more of the Made Of Diamond variety. As a side effect, his weight increases in proportion to his defenses, meaning he can't swim (not that this is a problem since the authority also apparently lets him survive underwater indefinitely). He managed to tank a hit from the Boar that pulverized the building he was standing on without a scratch and survived the Stallion with only a sunburn despite the fact that Steel Authorities are supposed to be weak against high temperatures.
Power Incontinence/Superpower Meltdown: His "Curse of Rampage" authority, which strengthens and/or activates mystical power, while sending them out of control. Hence making using Authorities a risky prospect, at best. Unfortunately, he's not immune to this power, so he also loses control.
Curb-Stomp Battle: In Volume 4, first against Liliana who tried to stop him from cutting the Heraion, then against Erica, to stop her from helping Godou. He defeated both of them in one blow without using any Authorities. In Erica's case, she didn't even see how he hit her.
Demonic Possession: In his Backstory. Prior to becoming a Campione, he was possessed by the divine spirit of Saint George and traveled to Ireland, looking for deities to exterminate. Nuadha defeated George and freed Salvatore, but Salvatore kept on fighting anyways, leading to him becoming a Campione.
Master Swordsman: Probably the best swordsman in the series. Even without using any Authorities, he can cut through objects harder than steel and keep up with the Raptor's Super Speed. He became a Campione by stealing the sword of Heretic God Nuadha, then beating him in a sword fight, despite the fact that Nuadha's sword shouldn't have been able to harm him.
Required Secondary Powers: No matter how big he makes his sword grow or how heavy his "Man of Steel" Authority makes him, his powers will make him strong enough to move normally. He actually exploits this in battle to give himself Super Strength.
Un-Sorcerer: A mild example. In an organization full of Magic Knights, he was the only member unable to use any magic. Not that it bothered him, since the only things he's ever really cared about, both before and after becoming a Campione, are refining his swordsmanship and fighting strong foes.
Voiced by: Ai Kakuma (Japanese), Meg McDonald (English)
Badass Adorable: Stopping Sun Wukong from moving, while trapped inside his stomach? Yes. Her Anti-Magic can also work to an extent on Campiones and Heretic Gods.
Cool Sword: When she wielded the magic sword Zanryuuto it combined with her Disaster Purification allowing Sun Wukong to be released.
Luo Hao's apprentice.
Badass Adorable: He is stated to be able to defeat 5 of the 7 Campiones in unarmed combat, given that these people have killed gods, yes, he is this. The adorable part comes because he is 14 years old.
In a Single Bound: Is a master of the Daoist spells of movement, which includes Leap.
Another Hime-Miko associated with the History Compilation Committee and allied with Godou. More involved with the organisational side of things and as such doesn't get directly caught up in Godou's schemes.
Bifauxnen: Wears men's clothes more or less constantly, even dressing as a priest rather than a miko when performing her religious duties.
The Casanova: Unlike Godou Kaoru is well aware of the reaction she inspires in girls and enjoys it.
If It's You, It's Okay: She inspires this reaction in the girls she dates when they find out she's actually female.
One Of The Guys: Many of her interactions with those like Godou and Amakusa. She even manages to get along with confirmed misogynist Lu Yinghua (though its unclear if he knows she's female).
Two-Timer Date: It's observed that its something of a minor miracle that Kaoru manages to avoid running into the trope.
