Bakekujira are whale spirits known as a yokai who haunts the sea seeking revenge on humans. While this is partly true not all bakekujira are set on causing chaos. There are some who are sweet but do have a lower vibration from the way they passed. When you invite one in your life they make great companions once they get used to you, acting as a comfort. While the dark art spectrum of these spirits handle revenge they are also feral and so this is something that for the safety of you and your spirits I will not conjure. Basically what you are doing here, is providing the gentle giants compassion and warmth. A friendly face to raise their vibration back to a normal state and regain a normal form. What we feel emotionally can effect the way our astral appearence looks if constantly dwelling on that said emotion. This is not unlike ghosts who when are connsumed with negativity start to take on unfavorable figures.
