Beautiful and compassionate Dr. Brezziana meets the infamous Dynamax Pokemon 'Eternatus' for the first time. Not only does she possess a gift to understand Pokemon language but also descends from a lineage of scientists that studied Dynamax energy for over 3,000 years. When she helps a wounded man at Lake of Outrage, she has no clue that this man is actually Eternatus in disguise.

One law Arceus enforced at the beginning of time: Every mythical Pokemon must sacrifice a portion of their great power and hide as humans among the world. When Hoopa refused, his true form was chained into a dark prison bottle forced to live every day as a human or small Pokemon before being cast into the chains of darkness every sunset. Until a girl enters his life.
