Episode 1 "A New Life"Edit
After serving an after-school punishment, Kazuki Muto is pursued by Mita, a professor at Kazuki's school that is revealed to be a homunculus that resembles a giant cobra. As he flees, Kazuki runs into his sister Mahiro who had gone to check on him. Kazuki tells Mahiro to run while he holds the homunculus off, but instead Mita emerges from the ground and swallows Mahiro whole.
Shortly afterwards, Tokiko Tsumura, an alchemical warrior, arrives and destroys Mita, freeing Mahiro from his stomach.
- This scenario is adapted from Chapter 1 of the Buso Renkin manga
- This scenario differs from the original manga, in which Kazuki Muto is devoured by Mita as well, and, after awakening his powers, rescues Mahiro by bursting out of Mita's body
