3 months before Minami's arrival , Seo and Varmoth just arrive to the Sanctuary after their hunting at the West building. They continue to walk and chatting with each other until they have reach to a certain place.
Seo: "Oh we're here already ?. It sure nice to talk with you today but I have to go now."
As he begin to walk separately from her , suddenly;
Varmoth: "Um!!"
Seo: "Hmm ? , What is it ?"
He make eyes contact at her as she gaze away from him. Few seconds has passed without saying any words , Seo begin to grow concern.
Seo: "Varmoth-san...?"
Varmoth: "I'm sorry it's nothing. Well , I'm going now."
She begin to run to the opposite direction from Seo. After she make some distance from him , she's stop and turn around then she give a waves at him while saying;
Varmoth: "I'll see you tomorrow."
Seo respond with a waves then say;
Seo: "Yea , see you tomorrow."
As he look at her departure , a man with a katana appear not far from him then he begin to walk toward Seo from behind and ask;
Man with katana: "Excuse me..."
Seo: "Hmm ? , yes may I help you ?...."
On the next day , Varmoth is on her way toward the meeting point were they last met. A moment later , she see Seo is standing waiting for her. That's what she thought as she see another man with a katana greet him then show him the way as Seo follow that man.
Varmoth: "(That's unusual. I have to follow him in case he's in danger.)"
15 minutes later at the West building , They arrive at the meeting point where they are surrounded by tall grasses. Seo wasn't sure about the place they're at , so he ask;
Seo: "Hey...you do aware that today is those creature's hunting season right ?. I don't think it's safe for us to be here."
Man with katana: "Yeah...."
As he take out a handgun from his shirt and point it at Seo;
Man with katana: "And that's why I brought you here...for a duel."
He then point his gun toward the ceiling and shoot 3 rounds of bullets.
Seo: "What are you doing !?. Who are you ?"
Katashi: "I'm Daisuke Katashi. As you can see , I am a samurai. We have less than 2 minutes before all pack of creatures arrive. So , what would it be ? , will you fight with me or die having both of us eaten by them."
Without hesitation , Seo unsheath his sword and guard up his sheild despite that he have a chance to escape but it would be an act of coward to run away and leaving him behind. So , in order to save him , he have to fight. Katashi then throw away his gun and draw his blade. Thus their duel begin.
Seo keep an eye on him for a moment until a blow of wind pass him by as he is surprise that Katashi is already right in front of him even though he didn't blink. He lift his sheild as Katashi swing his blade at it and making him immobilize. He swing his blade toward him again but this time , Seo counter his attack with his sword and bash him with the edge of his sheild. Katashi manage to block that bash with his blade but it make him push away by the force of it. Seo proceed to dash forward as well as Katashi then they soon swing their sword at each other. As their attack clash , it create a big wave of impact where many trees were cut down behind Seo while the tall grasses are swing around violently and a big boulder were crushed into pieces behind Katashi. A brief moment later , Seo and Katashi are now exhausted because of their constant attack and defense towards each other. Thus their duel end up as a draw.
Katashi: "you are a really great fighter , Seo-san. I didn't expect you can stand your ground longer than I thought you were."
Seo: "Same goes to you. I've never been catching a breath from a duel since long ago."
After that , Katashi walk toward Seo and reach his hand to him.
Katashi: "Knowing somone stronger such as you is reassuring. So , would you mind to take me as part of your team ?"
Seo is pause as he look at Katashi's hand. Then , he gladly accept his offer and shake his hand in return. Now that they are now allies , suddenly , a bullet is coming through between Seo and Katashi's head and hit the center of the incoming Gaoru's head appear out of the bush near them. Seo look to his left to see that those bullet is coming from Varmoth's sniper who happen to be watching over him.
Seo: "Seems like they're here already huh ?"
Katashi: "We're not going out of here safely until we kill all of those creatures."
Soon after many Gaoru appear from every direction and surrounded Katashi and Seo as they facing their back toward each other. Seo and Katashi then attack Gaoru that stand in their way as Varmoth give them cover as she snipe those creatures who try to get near them on their blocking view.
8 days later at the Team 2 headquarter;
Tozen: "So you want to establish a new team ?"
Seo: "That is right..."
Tozen: "Who would have thought that you want to form a team. It may take a long time for your team to be official."
Seo: "I'm fine with that."
Tozen: "Very well then , so who are your team members might be ?"
Soon after , two people step inside the room and stand at both side of him.
Tozen: "I see , that is very interesting teammates you have there. A girl named Varmoth and a lone samurai , Daisuke Katashi. Now that the three of you are meet the member requirement , you are hereby a temporary active team 9."
That is how Seo and his friends as a team formed.
