The Crystal Monster that is first shown on television might be the strongest Crystal Monster in Jarbon
The announcer on TV have said that the Crystal Monster is taking on it's new form, but what new form would we see about in the future? Koji's father was either divorced, missing, or already dead
So far in the series, we haven't seen Koji's father yet, but in Chapter 8, Natsuki Kiyoshi, Koji's mother, was crying at the end of the chapter when she looked at the flower, which would resemble the flower that her husband gave her before he disappeared, or died. Later in the second saga, Marc revealed that Koji has his powers from his father. Koji would never become a legal Crystal Brawler if Roakijushiku didn't climb up his window
He wouldn't even meet his friends, or many of the Crystal Brawlers, and he wouldn't even meet the 9th graders. Roakijushiku might have been kidnapped prior to the series
When Roakijushiku stated that he have known about the Furious Five before, he might have been kidnapped, and taken away from his family. Koji's father's disappearance is the reason why he studied about Crystal Monsters all these years
His father has been gone as long as he remembers, so he was depressed and upset that his father left. So in order to cope with his father's absence from the family, Koji took up researching Crystal Monsters, in which his father used to be a Crystal Brawler himself. Koji might have been bullied in Elementary School
When Shinju mentioned that he announced his dream to become Master Champion, you can see the classmate's annoyed face. He might have been picked on, called names, made fun of, etc. Shari's father is also an inventor and scientist
The first Furious Five gang we saw in the series might kill Koji(roara)
After they were reported by Koji, Julia became so enraged by this that she plans to kill the main character of the series. The two girls aren't really Aoha's sisters
It makes no sense that they are alike due to their appearance. Koji might have a secret interest in Aoha
Koji instantly cleaned up her garden house, what else? He's protective of her, he touched her hair for the first time, and he hugged her first. The reason Ryou was kicked out from Brawler School was because of drugs.
Ryou is 19, and he might have a drug problem. He didn't tell anyone about it, but he discovers one of Shari's inventions, and uses it to get high somehow. Koji lied to Roakijushiku when he asked him if he knows how to plant a flower.
Koji and Aoha were the first students to ever ride the cart in the School Tunnel
Kojiroara and Akimere didn't actually defeated Shinjuka
In Chapter 10, Shinjuka defuses in order to dodge the attack. Dragonar was abandoned by a former rock star
It might happen because Dragonar was also around the Orbon region where Makoto lives. Koji and Makoto are Clueless Chick-Magnet/s
Lots of girls have found them attractive, even Sora thinks Makoto is cute. Aoha, Akane, and Sachie is even after Koji. Makoto is sexually attracted to Koji, even at his debut
Makoto has been smitten with him, and he blushes when he asked Koji for his phone number.
