Gamushiro & friends 8L

Fig: Gamushiro & friends 8L bag structure. Includes DPC Recovery, which involves placing the extra piece in a specific spot compatible with a DPC setup.

Gamushiro & friends 8L is a family of 8-line PC opener C-spin setups.
Despite differing Bag 1 setups, Gamushiro & friends 8L often converge into one of the same couple of congruent residues on Bag 2.
Furthermore, solves on Bag 3 often end with holes of a congurent shape created after placing few pieces, which are achievable from multiple different residues.
Additionally, multiple of these setups are named after sweets (Gamushiro itself a sweetener).
These similarities explain why these setups get along so well, hence friends 🫂

C-spin openers do upstack on Bag 1, TST on Bag 2 and a 5-line PC (often involving TSS+Tet/TSD/TSS) on Bag 3.
