There are two, namely "Dearest" and "The Sorrowful Witch Platycodon grandiflorum".

At dusk, the background music is the sorrowful witch Platycodon grandiflorum, and if it is the scene where Inuyasha and Platycodon grandiflorum are alone, it is the pure music version of Ayumi Hamasaki's Dearest.

The soundtrack of Inuyasha's Final Piece is a complete reuse of the soundtrack of the previous TV version of Inuyasha. ?

Extended information:

Inuyasha's profile:

1. The hero of Inuyasha's works (Inuyasha/ぃぬやしゃ)

is a semi-demon, who was sealed by Platycodon grandiflorum for stealing the jade of four souls fifty years ago, and after the seal was lifted, he wanted to become one.

2. The heroine of Higurashi Kagome's works (Sunset かごめ/ひぐらし かごめ)

She is in the third grade of junior high school and lives in Tokyo in 1996. Because of the four-soul jade in the body, I traveled from the bone-eating well to the Warring States period 5 years ago, where I met Inuyasha and others. Because of the corpse-dancing crow incident, the four-soul jade was broken and scattered everywhere, and I began to set foot on the road to find the four-soul jade.

3. Sesshomaru (Sesshomaru/せっしょぅまる/)

Inuyasha's elder brother, but different from Inuyasha, is a true purebred monster with unfathomable strength and extremely poisonous claws. Conceited in his own blood, he can't tolerate such a semi-demon as Inuyasha. Clinging to his father's relics, he despised human beings, but changed after meeting the bell.

4. Seven treasures (seven treasures/しっぽぅ)

The fox monster wants to avenge his father with the help of the jade of four souls. After revenge, I set foot on the road to find the jade of four souls with Inuyasha and his party. Because I am a weak monster, I will use some illusions to protect myself.
