No, it was for something else, Liz specifically said that the effect had worn off despite it not being an hour yet, dude, and you also got things confused...Inoda didn't say ANYTHING, it was LIZ who said the effects of the COLLAR lasted for one hour after the 'master status' changed XDXD (Inoda genuinely was so retarded he thought Liz was going full tsundere on him and obeyind him out of her OWN free will, he's taht dumb and deluded

) No offense King, i respect you, but it's hilarious you said that about people ot understanding Fujino when apparently you misunderstood how the whole thing went ;P
But yeah, back to it, it's very likely that the boosted potion just stopped working after Inoda left Yui's vicinity, so eyah, this was just to clarify that Yui has limits, most likely exclusively centered about how she can help Inoda NTR girls in the plot but not solve the plot with a snap of her fingers XP
