Today’s challengers have different methods of protecting themselves from despair or harm, and both will defend their respective methods without hesitation. Shirakiin Ririchiyo believed that everyone she had met or would meet, including her own family, had a motive for being nice to her. In addition, she was unable to express her true feelings without facing opposition. To avoid further despair, she decided to put up her own barrier and act distant to everyone she met. Her servant embarrassed himself in public to convince her that his kindness was sincere. In contrast, her opponent, Araragi Karen, prefers offense over defense, and will openly say what’s on her mind. Accordingly, she uses her strength to defend herself and others, while fighting evil alone for the sake of justice. Her own brother had to fight and win against her to prove that she didn’t have to fight alone and could ask him for help. Both are spending their first year in ISML, although Karen has tournament experience from reaching the Top 32 of KBM last year. Will Karen sting her opponent and win her first Regular Season match, or will Ririchiyo use her demon powers to dispose of her opponent?

Who would you rather have? A sister who is obsessed with anime and cosplay, or a secret agent that protects you from danger? Hasegawa Kobato is your average young girl who yearns for her brother's affection—almost to the point of developing a brother complex. In front of strangers, she is shy and avoids interaction. Due to her personality, she doesn’t want to make friends, even though she is popular in her school. She gets jealous easily if her brother pays attention to girls other than her, and often throws tantrums so he will take notice of her. This is all due to her being afraid of losing him, as he's the only one she can rely on. Moving on, Roromiya Karuta is a kindhearted girl who likes to eat a lot. She is also one who will always render her help if others need it. Despite being helpful and someone who is cheerful and carefree, she has trouble making friends and yearns for them. She is also very intelligent and observant as she knows all the minute details about the situation she and the people around her are in. It's time to ask yourself a question: who would you rather have by your side?

The cunning girl who always has tricks up her sleeves, or the girl who was created out of virtual reality? We present to you Momo Belia Deviluke and Yui-MHCP001. Momo Belia Deviluke has a side she never shows to anyone except the person she loves. A rather lively girl, she drags others into her plans, and often is the one who lightens up the atmosphere. However, she is extremely protective of her loved ones. She would do anything so long as it gets them out of danger. Besides that, she is very considerate, as she spares a thought for others and wants them to experience the feelings of joy and happiness of being with the person they love. Next, we have Yui, a kindhearted girl who is bad at dealing with negative emotions due to her always experiencing it through others. After being with her "parents,” she became more cheerful and often tried to lessen the mood whenever it felt heavy. She is also extremely protective of the people she loves, and would do anything—even if it means sacrificing herself to save them from harm. With them facing each other, upon whom will victory smile?

After their brief meeting back in the Preliminaries, the time has come for these two girls to meet each other officially on the stage of the Regular Season, to show each other how much they have changed. Currently the lowest ranked Sword Art Online character in the overall standings, Silica, just like all her comrades from the same series, has been unable to keep up with her outstanding performance during the Preliminary Phase. The skillful Beast Tamer needs nothing else but to win as much as she can to cheer on her friends. Over on the other side, Akemi Homura is not any better. With several anti- Madoka ☆ Magica voters doing all they can to drag her down, the lonely mahō shōjo can do nothing else but clutch onto the hope of another upcoming film and try her best. They are not strong and powerful, nor have the strength to punch out their opponents, but both of them are giving all they have.

Round four of the Amethyst Period brings two former champions of ISML together in one arena. Katsura Hinagiku, President of the Hakuō Academy Student Council, will face her toughest opponent, Akiyama Mio, the bassist from Hōkago Tea Time. Hinagiku, who sees herself as weaker than before, can only hope for some strength left in her to surprise her opponent, though it will still be an uphill struggle. Her status as champion of ISML 2009 will be at stake here. Meanwhile, Mio is still in a comfortable situation, but must do something to assert her power. Her charms as a bassist and champion of ISML 2010 are alluring to a lot of people, making her struggles feel brief and mild, and culminating in results that are quite satisfactory. But she should not be one bit off guard, and fall into an abyss of her own making. When these two champions face off against each other, who can prove that she is the true one?

This round of the Amethyst Period brings together two girls who are complete opposites of each other. Introducing the first girl, we have Kuroyukihime. Kuroyukihime is an intelligent girl with a sharp tongue. She gets jealous easily and often tries to distance others from her loved ones. Though she might not seem like it, she can manipulate others to get them to do something she wants, or rather, to annoy them. She is also a calm person, able to keep her poise when the odds are stacked against her. On the other hand, we have Honma Meiko, or in short: Menma. A girl who is naive and an airhead, she is always cheerful and likes to hang out with her friends, though she often experiences loneliness and gets depressed easily. She always tries her best to lighten up the atmosphere; however, many a time her efforts do not pay off. She is determined, however, to accomplish the promise she made even if it means she has to sacrifice her life. The time has come for you to decide whose personality you like.

On this round of matches, the sky suddenly turns... pink for some unknown reason. On one side of the field, we have Louise Vallière, a magician well-known for her other name, "Zero". And that is only because every single time she casts a spell, it fails, usually leading to an explosion. That must be what gives her that extra "bang" in her tsundere personality. On the other side of the field, we have Yui-nyan, at least that's what she calls herself. She used to just be a big fan of her favourite band, but when the lead guitarist suddenly disappeared, she stepped up to the plate and took that position. She's also quite intelligent and hyperactive. Now in this battle of Pink, where will your votes go?

If this was a battle of laziness, then these two would definitely be on top, even though they might be at the bottom of their respective classes. Hirasawa Yui is a girl who, when focused on doing one thing, does it extremely well. At first she knew nothing about music, but when she entered the Light Music Club, everything changed. She transformed into an excellent guitarist, although she still makes a few mistakes from time to time. But then again, let's not forget Izumi Konata, a 100% otaku to the bone. Her priorities are her manga, anime, games, and definitely not studying. Though when she does study, she can get amazing scores, like the people who study days prior to an exam. It's time to vote now, so to which girl will your precious (or lazy) votes go: to the Guitarist, or to the Otaku?

The sky suddenly darkens with the arrival of these two girls on the battlefield. Both possessing extraordinary powers, which one will prevail? C.C. is a girl who holds the "Power of the Kings," a power only given to those whom she deems worthy. That's only one side of her. The other side of her is all about pizza. Yes, pizza. She loves pizza so much that she can't stop eating it. Speaking of addiction to food, Tachibana Kanade also has one: mapo tofu. And not only that, she has a power called "Guard Skills," which gives her a blade on her hand, the ability to evade bullets, and many more. Although she may have that power, she has a gentler side to her that none of her friends knew about. So to which foodie will your votes go to: Pizza or Tofu?
