Aha is one of the many Aeons that reign supreme over the Honkai Universe. Being the Aeon that resides over the Path of Elatiaon, he takes on the form of a large shadowy figure, hidden behind a vast amount of vibrant pale circus objects, including multiple shining orange lights shining down on the circus objects. He is incredibly happy and outgoing unlike most Aeons, being quite playful and definitely mischievous at that. He enjoys human companionship unlike most Aeons.
