Thanks for the chapter!
Glad MC switched to money instead of Estel for bet. Even if 100% chance of winning, which this isn't, should never bet companions as it's insulting and suggests view them as a commodity or item can use or toss on a whim rather than a respected and trusted comrade. Besides, that guy didn't offer one of his companions in trade if he lost and money or items wouldn't equal Estel's value.
@Cinnamonalt Think used smartphone instead of glasses to scan to hide fact scanning the guy with smartphone and buy time to look over info using the glasses. If he used glasses the guy might have caught on that MC was doing something if just looking right at him with thousand mile stare and distracted.
@Liquidxlax Be too risky if revealed them as summons. Considering haven't seen any other gatcha girls chances are only him and possibly other otherworlders transported there can do summons so people might think he's delusional or using that excuse to objectify the girls and not treat them as people. Or if they do believe him they might consider the girls as either abominations or not people who can be abused however they want. Also, has no way to prove they are summons as can't summon anyone else.
