After testing the ability of their "Duel Avatar" over and over again, they were familiar with their ability.
In terms of the fighting ability, both Haru and Tabane were the strongest among the four of them.
Charlotte's ability was quite good since she was a long-range fighter and didn't need to fight against the enemy from nearby, but Sumire was a bit bad since her ability was a bit hard to use at some stage within the game, especially when there wasn't any metal beside her.
The names of Duel Avatars are constructed from two things: a color and a noun. The color can apparently be anything, and the noun can also be any of a great number of things. The Duel Avatar's actual color is not changeable, though their appearance may change color slightly in extraordinary circumstances.
The players of Brain Burst have divided the color spectrum into three primary colors: blue, red, and green. There are also other colors such as yellow and purple which are included in a secondary color. Besides those five colors, there are also other colors such as black, white, and metal colors.
Each color has its own trait such as blue with close-range combat.
Haru's name was "Ocean Stingray" and he was blue, which meant he was good at close range combat.
Charlotte's name was "Maroon Owl" and she was red, which meant she was good at long-range combat.
Tabane's name was "Sunset Lop" and she was included in a yellow color, which meant that she was good at indirect attacks. It was also the reason why her special move was "Terrain Change" that made her able to change the terrain during the battle.
Lastly, Sumire's name was "Lilac Deer" and she was included in purple color, which meant that she was good at both long-range combat and close-range combat. But her fighting skill wasn't that good and she couldn't utilize her fighting ability that skillfully yet.
However, it didn't mean that Sumire would give up since she was sure that she would get better over time.
In the end, after they tried several times, they would make a team of two and play the tag match until they had become Level 4. They had decided to choose to play in a tag match because it was faster to gather a "burst point" to raise their level.
If they played a normal match then they would only get 10 points when they fought the same level opponent, but if they were doing a tag match, they could get 20 points even if they were fighting against the same level since they needed to defeat two people. It took 300 points to raise their level and it would take a very long time if they decided to do a normal match.
They needed to raise their level to level 4 as soon as possible so they would be able to enter "Unlimited Neutral Field" since inside that place, they would be able to hunt freely and get points faster.
The first team consisted of Tabane and Charlotte. Then the second team consisted of Haru and Sumire.
Charlotte was alright since she was a long-range fighter and her job was to support Tabane.
Tabane's ability at the fight was very good since she might be the strongest human in her world besides Chifuyu.
Haru had decided to accompany Sumire since he knew that she wasn't good at fighting.
Sumire's ability was magnetic manipulation and she could attract a player with a silver color since they were made of metal.
After that Haru could slay down the enemy with his stinger sword, defeating them in process.
Haru realized that his stingray shape was quite a disadvantage and his means of attack were also limited. It might also be the reason why his tail's power was really powerful.
However, even if his shape was a disadvantage, he also had his own advantage.
His stingray shape was different from the normal humanoid shape and even if the body shape was quite wide, he was flat. He could disguise himself in his surroundings and it would be very hard for the other players to attack him unless they were nearby.
"Please take care of me," Sumire said.
"No problem." Haru nodded.
"Char, let's do our best!" Tabane smiled and hugged Charlotte.
"....."
Charlotte was speechless, but she had gotten used to Tabane's antics. "Yes, please take care of me."
"So when are we going to have a battle?" Tabane asked.
"Do you want to do it right away?" Haru asked.
"Why not? I want to see the combination between me and Charlotte during the battle as soon as possible!"
Tabane couldn't have a real battle against Haru before since this guy was very slippery and his skill was too perverted. Even though she had tried to trap him, this guy could use his skill to run away from her.
"Then, we can start to connect to Global Net to search for the opponent," Haru said.
"Oh, right! I've almost forgotten something!" Tabane slapped her forehead and said, "I've created a program which has a similar function to "Brain Implant Chip", do you want to use it on your "Neuro Linker"?"
The Brain Implant Chip (also known as the B.I.C (or written as BIC)) is an illegal chip implanted in the brain. It can be used in the same way as a Neuro Linker.
It was quite a special thing since it had a function to keep their name off the "Brain Burst" matching list so no one would be able to ask them for a duel so suddenly.
Tabane had created a program that had a similar function as BIC so no one would be able to see their name and no one would able to request them for a fight so suddenly. She felt that this program was quite necessary since she didn't want to be disturbed when she wanted to take a break outside and she also didn't want to turn down her Global Net since it was necessary.
"Well, let's use it," Haru said.
They nodded and downloaded the program from Tabane. They knew that this program was necessary so no one would trouble them when they went out.
"I've named this program "Kage-kun" (shadow), it is a good name, right?" Tabane said with a beaming smile.
"Yes...." 3x
The three of them answered with a bland tone.
"Moo!"
Hearing their answer, Tabane puffed her cheek and seemed quite annoyed by their bland reaction.
"I almost forgot to ask this question," Sumire said.
"What's wrong?"
"Do we need to enter the middle school of the main character?" Sumire asked.
"What do you think? If you're alright with it then let's enter middle school." Haru didn't really mind entering middle school once again, however, he felt that it wasn't that necessary.
"Hmm...."
It wasn't that necessary for them to have contact with the main character and other characters, but it would be quite weird for them to stay at their home all the time.
"I think we need to go to middle school or else someone might think that we're a hikikomori," Charlotte said.
Hikikomori are reclusive adolescents or adults who withdraw from society and seek extreme degrees of isolation and confinement. Hikikomori refers to both the phenomenon in general and the recluses themselves. Hikikomori has been described as loners or "modern-day hermits.
"Alright, Tabane-chan is going to make her middle school debut again!" Tabane smiled happily.
Haru nodded and said, "Alright, let's become a middle school again, but let's do it next week and use this week to get used to the battle on "brain burst" to level up as soon as possible."
"Yes!" 3x
After everyone agreed, they decided to start the battle right away.
Haru with Sumire and Tabane with Charlotte, each two of them created a team by themselves before entering the game.
"Burst Link!" 4x
The world turned blue and they started their battle with other players in tag match.
