>>107575412BTB didn't really "revive" the branch, they only delayed its downfall by a few months. Kinda like how AR Live prevented the Q4 2024 revenue from dipping below a billion yen (1,075 MJPY with vs 916 MJPY without) but was a one-time thing and couldn't salvage the subsequent quarters.
Imagine using a fairly large mop bucket to bail out a sinking ship, except the bucket is water-soluble and gradually turns into a sieve with continued use before dissolving like a spoonful of sugar in the ocean. BTB's debut buff was their latest such bucket.
Whatever sort of "bucket" they may have on hand to salvage the branch's Q3 performance, they have a little over 7 weeks remaining to use it. The only thing I can think of would be if they give BTB their 3D showcases next month, and even that will necessarily be a one-time thing.
