Rebel Biwa Bassist
Benben's mysterious band costume. She used magic to transform her biwa into a bass guitar.
Shunshou (a Touhou LW original) refers to spring evenings. This is appropriate for Benben who is a tsukumogami of a biwa, a Japanese lute. Benben is endowed with Wood Essence, with the biwa being an instrument made out of wood, and Moon Essence, with her aptitude for adapting to any situation.
This is Benben and Yatsuhashi's ability as tsukumogami of instruments. Tsukumogami are tools that have attained sentience, so being able to make sounds and perform by oneself could be taken for granted, but since the two of them only became tsukumogami recently, being able to perform without a musician is surely a joy. Benben is especially happy with becoming a tsukumogami as it has made it possible for her to have a sisterly relationship with Yatsuhashi and to talk with various humans and youkai. There was a real risk of the two of them reverting to plain old instruments when a past incident was resolved, but Raiko helped make it so that they could retain their human-like forms.
Benben Tsukumo's Spread Shot (a Touhou LW original). In this attack, she plays the biwa while telling a story about vengeful spirits, a priest, and an earless musician. Upon hearing this famous story, you will realize how terrifying vengeful spirits can truly be. However, you will also learn that if you write Buddhist Sutras all over your body, vengeful spirits will be unable to see you.
Benben Tsukumo's Focus Shot (a Touhou LW original). Bullets in the shape of a musical staff are shot out in this attack. The biwa was traditionally played by using its own musical notation, so the fact that Benben knows staff notation means that she somehow gained access to this knowledge from the outside world, or that her biwa was still in the outside world until recently. Regardless, it is thanks to this universal language of music that she can so easily play songs together with Raiko and the Prismriver Sisters.
Benben Tsukumo's Spell Card. In this attack, she plays a tune inspired by a classic military epic. The Tale of the Heike starts with the sound of Jetavana's bells, which echo the impermanence of all things. A time comes when all those who live in prosperity must fall. The tsukumogami may have taken this as inspiration in regards to Gensokyo's current regime (the sages etc.) in a past incident.
Benben Tsukumo's Spell Card. She shoots out vicious bullets in the form of musical staves. Like tsukumogami, musical staves do not have sentience at first. Staves imbued with maliciousness may be a type of kotodama, a spirit that dwells in words, or perhaps they could be like the musical note bullets, where the bullets are the embodiment of sound itself.
Benben Tsukumo's Last Word (a Touhou LW original). This attack is a manifestation of the resentment that some tsukumogami have. It is apparently based on a story of an old biwa youkai who takes revenge by burning down its former owner's residence. Tools should be treated with care and given a proper send off when they can no longer be used.
