Oneechan ga Kita: Hajimete no… Kitaa!

When a new step-sister enters the picture, it's usually a cause for at least a little awkwardness. For Tomoya, that understatement doesn't even begin to cover it. Ichika is not just any older sister; she's an energetic, affectionate, and utterly clingy force of nature who sees her new younger brother as the absolute center of her universe. Get ready for a whirlwind of enthusiastic hugs, doting attention, and a complete upheaval of Tomoya's once-quiet life. This charming slice-of-life comedy perfectly captures the delightful chaos that ensues when a well-meaning, if a little overbearing, sibling joins the family. Expect humorous misunderstandings, heartwarming moments, and a healthy dose of exasperated reactions as Tomoya navigates his new normal under the watchful, and very close, eye of his adoring onee-chan.
