# Single Strike Style Mustard (Japanese) #088 — S5I: Single Strike Master

## Summary

Mustard fills the frame in a rainbow-foil Hyper Rare treatment, caught mid-stride with a clenched fist and a fierce scowl, his red hair swept back and the colours rolling from green to gold across the textured surface. Single Strike Style Mustard in the Japanese S5I: Single Strike Master set arrived in January 2021 as a chase slot, and the Isle of Armor coach's following keeps this Hyper Rare in demand. The modelled guide sits at $4.89, down 5% on asks over 30 days with no copies traded; no PSA population is on file, and a PSA 10 would fetch about $50 against $65 in grading fees, so the only money in this card is finishing a set, not a slab.
