One of them was alchemy which most people dismissed as charlatanry, however Bakushaku sensed there was more to it and so he began to delve into its mysteries. To his disappointment he found that there were limits to how far he could go on his own. His studies had consumed a fortune and years of his life went by until he discovered the homunculi and the Kakugane which led him to a dead end. However, not long after he met Victor Powered, a traitor of the alchemist warriors, the two then joined forces. Victor was severely injured so in exchange for his knowledge of alchemy, Bakushaku promised to heal him when he had finished his research.

Twin siblings who are third year students in Ginsei Academy: Ouka is the Student Council President and Shusui is her vice-president, plus the Kendo Team Captain. The two are... well, quite close, plus they have an extremely disturbing and sad past that has left them deeply scarred.

  • The Ace: Shusui competes in kendo on a national level, is extremely popular with the girls, is intelligent enogh to be the vice president of the student council (behind only Ouka) and is...*ahem*...'bigger' than Kazuki and his friends.
  • Brother-Sister Incest: They are... CLOSE. As it turns out, there are very painful reasons behind it; and later in the series, they start opening up to other people and begin to relay less on each other.
  • Brother-Sister Team: But of course.
  • Dark and Troubled Past: Uhm. Oh, boy. They were raised by a lady named Mayumi Hayasaka; she kept them locked away in her home, and had them play "wedding games" among other things. When Mayumi passed away there, the twins (who were really young and sheltered, so they didn't really understand the concept of death) played with her corpse until it was rotten. Then they were found and rescued by others... and it turns out Mayumi was the lover of their dad and kidnapped them away from their parents. Who then rejected the kids, no longer considering them their children. They were Street Urchins until Shusui had an encounter with Dr. Butterfly and Moonface, and they were taken in by the L. X. E.
  • Expy: Of Tomoe and Soujirou from Rurouni Kenshin
  • Guys Smash, Girls Shoot: Shusui's Busou Renkin (Samurai X) takes the form of a katana, whereas Ouka's (Angel Gozen) is a bow.
  • Half-Identical Twins
  • Lady of War: Ouka is a skilled archer, and her Busou Renkin gives her access to an alchemic bow and arrows.
  • Yamato Nadeshiko: At first sight, Ouka is a perfect fit for the archetype. The truth is... much more complex.
