Trío de anime en dojo interior tenue con tensa anticipación

Anime style illustration featuring three young characters in a somewhat dilapidated indoor setting. On the left, a female character with spiky purple and black hair, wearing a grey kimono-like top with a blue pleated skirt adorned with white and green star patterns. She has purple eyes and a determined expression, with a katana tucked into her obi. In the center, a figure wearing a distinctive blue, circular mask with a red "X" symbol, clad in a white lab coat over a black shirt and blue shorts. On the right, a male character with spiky red hair and a light-colored headband, wearing a red cropped jacket over a black t-shirt, grey wide-leg pants, and a dark belt. He has an expression of surprise or concern. The background appears to be a room with wooden walls, possibly a dojo or a rustic building, with a punching bag visible on the left and some indeterminate objects or structures in the background. The lighting is somewhat dim, suggesting an indoor environment, with a slightly muted color palette. The composition focuses on the interaction between the characters. The overall mood is one of anticipation or intrigue within an action-oriented anime genre.
