His jealousy about Kirito who Asuna regarded as a man far stronger than him turned into grudge. Kuradeel even challenged Kirito on a duel but he lost. As the series progressed, Kirito lost to Heathcliff after an intense battle of defense and offense which forced him to join his guild. Kuradeel and Kirito met once more to train but now under the same guild. Kirito thought that Kuradeel already got over his past grudge against him, yet it’s the other way around.

Real Name:



PoH was the leader of “Laughing Coffin” an evil guild in SAO with only one purpose; get everything from the weak. Their main goal is to steal valuable items from players out of selfishness. They don’t want to finish the game but rule over SAO. Kirito described PoH as a master in using a dagger. Even Kirito was uneasy while telling the story to Asuna which is an evident proof that PoH is a formidable player. Nevertheless, his guild was wiped out after facing the alliance of good guilds. PoH’s body wasn’t found after the fierce battle so it’s assumed that he survived and eventually saved from SAO.

Leafawas Kirito’s partner in ALO. She helped Kirito understand the game and lead him closer to Asuna. Kirito’s charm and innate goodness made it easy for Leafa to fall in love with him. However, she eventually gave up on the feeling and was badly hurt in the process after knowing Kirito’s true identity. He is her brother, Kirigaya Kazuto. Leafa is quite skilled as a fighter in both online and real life. She even fought well against Kirito. Leafa’s support skills are also remarkable which was evident when she protected Kirito from the ferocious attacks initiated by a party of Salamanders. Leafa is one of the prettiest faces in the anime world and made Sword Art Online even more worth watching.

6. Klein, the Supportive Best Friend

Real Name:

Tsuboi Ryoutarou


Klein was Kirito’s first friend in SAO. Kirito taught him the basics in SAO and that marked the start of their weird but true friendship. Kirito decided to leave Klein and it was something our hero regretted about. Klein didn’t care at all and continued treating Kirito as one of the few players in SAO he can truly trust. Klein easily gets angry and hyped up if the safety of a friend is at stake. He is a strong player and already participated in various online games prior to SAO which is probably why he survived. He is a bachelor and always finds some time to seek for love but he usually fails in a funny way.

5. Asuna, the Love of Kirito's Life

Real Name:

Yuuki Asuna


Asuna is the main female protagonist in this series. She was among the many players trapped in SAO. Though she had the option to stay and be away from danger, Asuna decided to level up and help in beating the game. Such bravery is quite rare especially for a lady who seems to have no experience about playing an online game. Through hard work and determination in finishing the game, Asuna grew strong and eventually became the top guild’s vice captain. Asuna met Kirito during their early levels but haven’t but they took different paths. Kirito decided to be a solo player while Asuna stayed on a group. Their special feelings toward each other started to grow when Kirito found a rare ingredient which only expert cooks like Asuna can prepare. They ate together and decided to form a party afterwards. They cleared a hard dungeon together and their love story bloomed. After beating SAO, Asuna was left trapped in ALO because of Sugou’s doing. Kirito did his best to save her and bring Asuna back to real life. It was never easy yet Kirito managed to pass through all life-threatening challenges. This only proves how much he loves Asuna.

4. General Eugene, the Strongest General

Real Name:



General Eugene is one of the strongest ALO characters. He fought Kirito and almost defeated our hero using a rare sword that changes phase. Despite his brute strength and impressive fighting technique, Kirito managed to overpower General Eugene through his remarkable speed. Kirito used two blades and attacked General Eugene ferociously leaving him with no room to dodge or block. Kirito’s victory stopped the Salamander’s guild from laying out their plan to defeat the two other guilds at once. This made Kirito a hero in the eyes of many including Leafa who was so amazed about Kirito’s overall personality and fighting prowess. General Eugene suffered defeat but it’s evident that he is a man who keeps his word and has more than enough courage to be worthy of respect.

3. Fairy King Oberan, the Villain King

Real Name:

Sugou Nobuyuki


Fairy King Oberon was the self-proclaimed ruler of ALO. He was the one who took Asuna hostage. His treats trapped SAO players as guinea pigs for their experiment in mind control. The digital world would be in great trouble if Kirito failed to stop him. He is selfish and cruel. Kidnapping Asuna was part of his plan to disable their company’s owner, Asuna’s father, to dig deeply on their company’s activities. The project he initiated was of course illegal so Sugou Nobuyuki, Fairy King Oberon’s real identity, did his best to keep it a secret. Despite having GM privileges, Kirito managed to kill him in ALO. He ambushed Kirito in real life with a knife but our hero fought back and placed Sugou on his rightful place, in jail.

2. Heathcliff, Kayaba Akihiko's Avatar

Real Name:

Kayaba Akihiko


Heathcliff is the Knights of the Blood guild leader. He was tall, muscular, and very strong. With a huge shield, he easily defended against Kirito’s attacks during their duel. He won but it’s evident that he could have lost if he didn’t use his powers as a GM. Kayaba Akihiko is his real identity. He is the one responsible for trapping thousands of gamers in SAO. He claimed that is was simply a social experiment. It was a test whether the youth of today truly knows the meaning of life and to determine how they would react to a challenge where their life is at stake. He committed suicide after SAO was at the brick of its end but he was able to transfer his consciousness on the game itself. Thanks to him, Kirito was able to defeat Fairy King Oberon so we can’t really consider them as an antagonist in this series.

1. Kirito, the Black Swordsman Solo Player

Kirito is the main male protagonist in Sword Art Online. He played SAO to escape reality and fight boredom. Kirito was a beta tester so he was confident that he won’t find any problem about playing the game but his expectations were all wrong when a strange figure appeared in the sky during the pilot day of SAO and announced the drastic and alarming changes in the game. Logging out was impossible until the game is defeated. Kirito worked hard in clearing one dungeon after another. As the challenges increase, he was convinced that soloing is far too dangerous so he decided to team up with Asuna. He fell in love with the pretty lady warrior in the process and his feelings encouraged him even more to finish the game as soon as possible and save Asuna. He eventually succeeded in defeating Kayaba Akihiko, who posed as Heathcliff. Nonetheless, he was the only one who woke up. He found out that Asuna was trapped in another game called ALO so he ventured on another journey to meet his princess and finally bring her back to real life. Asuna and Kirito’s love story is one of the sweetest I’ve seen in the anime world. Their chemistry never fails to excite anime fans and seeing them enjoying each other’s company after all the hard experiences they had on SAO and ALO brings joy to my heart like no other.

Kirito vs. General Eugene!

Where Yuuki?

Inori on March 14, 2017:

I have to say, the first half of the anime was pretty good but the other half is not, i was satisfied with Sao 2. But what i dont like in the anime is the characters especially kirito, he is frikkin op in some ways and asuna, she was cool at first but then became a damsel in distress

Akane on March 14, 2017:

what about yuuki or her sister, they are stronger than kirito. Konno Yuuki is known as Zekken (absolute sword) due to winning 67 DUELS including the one with kirito. And she created the eleven hit combo which i believe i is the most in ALO

Ushio on January 09, 2017:

Prefer Kono Yuuki

yuuki on November 13, 2016:

Yuuki is the strongest not only physically (by physically i mean in the virtual world) but also mentally. She has suffered a lot but is still able to smile and be happy.

Akumanen on June 04, 2016:

Asuna u are too cute.....

Anonymous on April 05, 2016:

1. Kirito (Dual-Blades)

2. Zekken - Konno Yuuki (Mother's Rosario)

3. Asuna (Mother's Rosario passed to her by Konno Yuuki)

4. Heathcliff

5. PoH or Eugene

Onii-sama on August 12, 2015:

Yuuki's sister, despite whatever they say about her, is featless and so cannot be quantified on how strong she is. It's like the Chuck Norris facts thing, a lot of people say a lot of stuff but none can be proven unless he is seen doing it.

No name on July 29, 2015:

What about Yuuki's sister Aiko/Ran. Yuuki said she was much stronger than her before she died. I think she should be at the top. Also Lisbeth and Argo and my favourite characters.

Kuroyukihime on July 14, 2015:

Konno Yuuki?

Onii-sama on July 10, 2015:

Kirito lost to Yuuki in the novels via outright losing than timing out. They were fighting 10mins. non-stop before he lost to Mother's Rosario. So yeah, Kirito got really rusty but he did take his fight vs Yuuki seriously.

Desu-gun even commented on how Kirito was really, really pathetic in comparison to his SAO days.

Unknown on April 26, 2015:

I think Kirito is the #1. Yuuki may have defeated him, but Kirito didn't really fight seriously. Well, he fought seriously, but it wasn't his best. Kirito said that he would only fight seriously if it involved life or death.

If there wasn't any time limit at all, Kirito would've won the tournament, and even Yuuki (or Zekken) got surprised on how strong Kirito really is. Kirito also goes easy on girls.

Onii-sama on April 22, 2015:

Strongest Characters as per showing

10. Post-Caliber Arc Kirito

Among the top echelons of swordsmanship in all games but loathes using his dual blades persona to go full power (see Sterben's 'You Suck' speech during

Phantom Bullet Arc implying Kirito dulled which is how he was able to dominate

in the first place other than that Kirito was being hesitant)

9. Pre-Integrity Knight Eugeo

He showed potential to surpass Kirito by Kirito's own words with regards to

swordsmanship. He was already almost on par with 1-blade Kirito.

8. Sterben (Shinkawa Shouichi)

Fought and actually was dominating a 1-blade Kirito for most of their fight in

GGO (though admittedly, Kirito was a nervous wreck and was using a weapon too

light for comfort according to Sterben's own words) and had to be momentarily

distracted by Sinon for Kirito to get his bearings back.

7. Integrity Knight Alice

No doubt incredibly powerful but still lacks high-speed combat feats to go
