The most popular and numerous basic species. Characterized by a black hat and blonde side-braids. Speech style: Speaks in hiragana-heavy Japanese, using phrases like "Take it easy!" (Yukkuri shiteitte ne!) and "Marisa is eternal!" (Marisa wa eiyun nano ze!). ・Personality and Role: Refers to self as "Marisa" and ends sentences with "-ze." Compared to other Yukkuri (like the Reimu species), they have higher physical ability and stamina. In a pack or family, they often take the "father/breadwinner" position, responsible for hunting (gathering food) and manual labor. ・Variations: They are depicted in diverse ways depending on the work, from proud and family-oriented kind individuals to "Scum Marisas" who are too prideful and look down on others, to "Dosu Marisas," giant mutants who lead packs with overwhelming power and charisma. ・Family: Father of Maricha. Has a wife named Reimu and another child named Remyu, but gives special treatment to Maricha, who resembles him.

A nickname for infant (akayu) or child (koyu) individuals of the Marisa species. Speech style: Characterized by a lisping, childish way of speaking, such as pronouncing "Take it easy!" as "Take it eashy!" (Yukkuchi chichieitchiene!). Extremely Fragile Body and Low Intelligence: Smaller than adult Yukkuri, they are so weak that a minor impact or a small step can be fatal. Because their intelligence is underdeveloped, they often fail to understand danger and end up destroying themselves. Complete Dependence on Parents: They have no ability to survive on their own and require the protection of a parent (Mommy/Daddy). Role in Works: While depicted as innocent and adorable beings, in abuse-themed works, they are often the first victims due to their overwhelming helplessness, or they are subjected to horrific punishment as "Scum Marichas" who inherited their parents' self-centered personalities.
