Synopsis: My Sp/lit Little Sister

Recently, Uiha and her elder brother Shougo have had minimal communication despite being close in the past. Uiha's attitude towards her brother has become frigid. Nevertheless, the situation flips when she discovers a replica of herself named Uraha by Shougo. Although Uraha looks exactly like Uiha, her conduct vastly differs; she shows immense warmth towards Shougo, desiring to bathe together and excessively clinging to him. With Uraha now part of their family, will Uiha and Shougo's previous connection be reignited?
