Valt:
You were a new student at Beigoma Academy and when the teacher was introducing you Valt jumped up and shouted, "Join the beyclub!" You said ok and at lunchtime you went up to the roof and met the beyclub. You've been hanging out with Valt ever since.

Shu:
You were a big fan of the Supreme 4 and one day you entered a tournament and you got to the final and you had to battle Shu. You battled hard but lost because Shu is so strong but you didn't mind. After the battle you chatted with Shu and became friends.

Rantaro:
You were Valt's sister and one day while Rantaro was at Valt's house he saw you. You began chatting with him and from then every day Rantaro came over to Valt's house you two would always hang out.

Daigo:
You had lost your pet cat and when you were looking for it you saw Daigo stroking it and giving it some food. You ran over and Daigo asked, "Is that your cat?" You nodded and said it got lost the other day. You thanked Daigo for finding it for you. You then became friends with Daigo over both of you loving cats.

Wakiya:
You were hired as a maid to work at Wakiya's house. At first he hated you and would always order you around so you'd always be super tired. Eventually you told him to stop telling you to do everything. He wouldn't listen so you told his parents and they told Wakiya to stop. He hated you even more afterwards but eventually he began to like you. You're now friends with him.

Ken:
You went to one of his puppet shows and after it you went to chat with him. You were both really shy but you became friends with him quickly. You'd go to every one of his puppet shows and over time you'd stop being shy and he became less shy too.

Toko:
He always saw you hanging out with the beyclub. He asked you one day if you wanted to be his friend so you said yes. He said you were like a sister to him, even more than Nika. From then on you'd always hang out with him after school and buy him ice-cream.

Ryota:
You were Daigo's friend and he always took you to see Ryota in the hospital. After he came out of the hospital you still visited him and he liked you a lot. So you became friends quickly and played with him every day.

Xander:
You trained at his dojo every day. You admired him and wanted to be as strong as him so one day you asked him how he was so strong and he said he would help you become strong too so he trained you and you became friends in the process.

Yugo:
You were Ukyo's sister and you always were there when the battled eachother and you liked Yugo so one day you asked him could you hang out with him. At first he didn't really like you but he soon softened. Now you're good friends and you make Ukyo jealous.

Ukyo:
He would always jump out on you from the shadows and scare you. You found it annoying but eventually you found it funny so one day you asked Ukyo how he hid in the shadows so well. He taught you his ninja skills so both of you jumped out on Yugo and scared him. He hated it but you and Ukyo found it very funny and you quickly became friends.

Quon:
You liked skateboarding and went to this skateboard park every day and he also went to the park and you watched eachother skateboard and gave eachother tips and stuff. You became friends after you tried to do a hard trick and fell and he made you better.

Zac:
You went to one of his concerts and after you got a chance to go backstage and meet him. You met him and fangirled a lot. Then you chatted and became friends and now you go with him to every concert as a backing singer.

Akira:
Basically the same as Zac's one because I'm lazy lol.

Ben:
You battled against him in the national tournament and lost but he liked the way you battled so he invited you to join his team. You said ok and you joined. You became friends over many days of beybattling.

Naoki:
You were his assistant and helped him with his experiments. You both loved science so you became friends. He said he never had a real friend because no one likes science as much as he did so you were really good friends.

Jin:
You could see ghosts and saw Jin's 323 spirit friends. It freaked you out but Jin said they won't hurt you or anything. You became friends with him but you still are freaked out over him and his 'friends'. But he can calm you down quickly.

Lui:
The same as Shu's but Lui didn't like you but you soon made him nicer. But he still loves to hate you.

I'm tired so I'll do a part two with the season two boys :) Tell me if I missed anyone in part one!!!!
