Was she increasing her demonic power or just accessing more of the demonic power she already had? Because devils need to mature and develop their demonic powers over time. For example, Rias could have the same level of demonic powers as Serafall. But what's the difference? Serafall is much older and has matured and developed her demonic powers. Rias isn't even 20 years old and is still too young for her demonic powers to develop all the way. Now do you notice how when Rias uses Extinguish Star, it takes a while to charge up because she is collecting a lot of demonic powers. Now as she gets older and more experienced the time it takes to charge Extinguish Star up would decrease due to her developing her demonic powers. Has Rias' level of demonic powers increased? I mean her base level of demonic powers. Not the amount of demonic power she's able to access.
