If Kuma serve these in a WWE "Big Four" pay-per-view to all the heel wrestlers and authority figures, they would be KO'd or drunk halfway during the event while the fans, face wrestlers and authority figures laughing at their drunken state.
The first time Reiji collapsed was from a Kongou dish... now to Kuma's killer cocktail. And that's already saying that he's a supersoldier already to go toe to toe with Abyssals.
I'm guessing that it has Spirytus Rektyfikowany in there or something assuming Reiji can up and tell Kongou to buy that thing. Or the Green Fairy.
When Hibiki is down like that from a drink, you know you're not coming back if you drink Kuma's cocktail.
Hibiki, too?!
One of my best kuma~Oh, let's look how good it rea...A dozen minutes later-

C-Commander!?
...W-well if you say that much...How can I refuse a drink, anyway?
