It drops you into Kazamatsuri's flower-choked streets like a lazy occult-club comedy, then spends thirteen episodes methodically burning that world down. This is the Key adaptation that refused to pick one route, so you get Kotori's forest, Chihaya and Sakuya, Lucia's gloves, Shizuru's earpiece and Akane's throne all stacked into a season built for one, and yes, the seams show. The pacing is genuinely broken in places, but the payoff is Kotarou rewriting his own body past the point of return while Gaia and Guardian tear the city apart around him. Kagari standing in the green with the world ending behind her is the image that stays. Fans of Clannad and Air know this feeling: the slice-of-life was the setup, and the summoners' war was always waiting. You either check out by episode four or you never fully leave.

Kazamatsuri is a modern city where years of tree planting have filled the streets with greenery and flowers, giving the place an odd, nostalgic feel. Tennouji Kotarou, a proud and nosy high schooler, can permanently rewrite parts of his own body to boost his strength or speed. A meeting with Akane Senri, known as the Witch and the lone member of the Occult Research Club, leads him to revive the club with Kotori, Chihaya, Lucia and Shizuru. Together they look into supernatural mysteries, and Kotarou learns the hidden secrets of each member. The story blends drama, romance, everyday life and the supernatural.
