The conference to defeat the sigma

After escaping from Takashi's 100 girlfriends and successfully entering the school council club room. She had safely avoided them all and locked the door to avoid being attacked by the mob of girlfriends. She then approached the person who was in the club room , the school council present , Dazai Osamu and informed him about Takashi's disruptive behaviour in the school. After a while of conversation and settling down , spoke Dazai: 

"Hmmm , yes indeed , Takashi has indeed disrupted the school environment and disturbed the romantic balance of the school. Shit. I'm supposed to be dawned upon! Not him! Why is this loser getting all the attention!!" 

Alya: "In any case prez, we need to do something or else the entire school will come after us. We need to restore the balance of the school. He calls himself a sigma. Sigma. I'm sick of hearing that word from that woman repellant Takashi! Just what on earth is a sigma even???"

Dazai: "Hold on Alya. Did you just say SIGMA??? Oh God...this is bad. This is really bad. If he truly is a sigma, then he is almost invincible , I'm afraid. Urban legend has it that long ago existed a man known as Monkey D Sigma. He was a charismatic and mysterious man who was righteous and was always on the grind. However , there was a witch who got jealous of his enchanting personality that upon meeting him one day, she turned him into an emerald! Rumor has it that anyone has this emerald gets his personality and is loved by people. This love turns into power which makes them very strong. The witch used this emerald to get his personality and she took advantage of people's love and wreaked havoc upon the earth! She was later defeated by Edge , a mage who originated from modern day Ohio. Edge sealed this emerald in Japan , far away from the reach of the Americans. If what you say is true about Takashi , the sigma male , then he must have used the power of the Sigma emerald"

Alya: "So..all we have to do is defeat the sigma make and retain the emerald right?''

Dazai: "Yes indeed. The sigma male appears once every 3 years and is known to be a threat to Alpha , gamma and Omega males. The sigma male must be defeated or else he will be too sigma."

As such , both Dazai Osamu and Alya Mikhailovnavich and other members of the school council decided to defeat Takashi Yamahiro , the sigma male and the last Sigma bender. One fine day , they surrounded Takashi Yamahiro.
