6

After Haru and Takumu reveal everything to Chiyuri, who doesn't take it too well, the two begin training to work as a tag team. Haru earns enough points to upgrade to level 2, though in his haste, he upgrades too early and is left with a low amount of Burst Points as a result. Takumu offers to share some of his points with Haru, but he declines, saying it would take all the honor out of fighting. Afterwards, the two go over to Chiyuri's, where they eat ice cream together and explain to Chiyuri about Brain Burst. It is here where Takumu gets the idea to have Haru hire a bodyguard known as Aqua Current to protect him until he gets his points up. As Haru goes through the procedures to hire Current, he inadvertently discovers it is actually a girl. Haru discusses things with Current, and then Aqua Current arranges a battle with two Burst Linkers. Aqua helps Haru to defeat them. Afterwards, Haru gains Burst Points and Aqua erases his memory because he knows her real identity and vows to never meet him again. Takumu goes to the hospital to meet Kuroyukihime, who activates her Burst Link and challenges him to a duel, during which she confronts him, asks him why he left the ken-do club, and why he wants to forcibly uninstall the Brain Burst program. During this, Takumu realizes how much Haru admires him. (Source: Wikipedia)
