星刻の竜騎士

At Ansarivan Dragonar Academy, every student is expected to bond with a dragon partner, everyone except Ash Blake, whose star-shaped brand has stayed dormant since enrollment. When his dragon finally hatches, it takes the form of a girl named Eco, who promptly informs him that she is the master and he the servant. The original light novel series follows Ash's chaotic reordering of academy life around a partner nobody expected, and a separate manga adaptation runs alongside it.
