Haradhanu Janaka

is the hard bow Noble Phantasm of Sita.Fate/Grand Order material III - Rama, p.254-263 translated by Kinalvin at Reddit.
The god of destruction Shiva's bow was handed down to King Janaka's Ancestors for generations. Gods, asuras and rakshasas tried and failed to lift it. Only Sita managed to lift as a child, without even trying. Janaka then decided he would only allow Sita to marry someone also able of lifting and string the bow. Later, Rama lifted the bow and snapped it in an attempt to string it. Her marriage with Rama was undoubtedly the greatest fortune in her unfortunate life.
Because she was summoned with the power of another version of Rama, she can string this Noble Phantasm despite not being related to King Janaka by blood.
