#yeeeeish....

I couldn’t help but be a bit stuck as to what the ‘no problem’ was exactly, but taking a look at the JP text for a moment:

“Well then, how about joining my organisation? A person in the organisation will have no problem if they know (its) secrets.” (rough)

Emphasis: 秘密を知っていて

So first thing’s first, no problem with Shuichi learning potentially... dangerous secrets? Curious... and a bit of lost context at that, considering this whole thing was supposed to be about the cost of losing games (even line length aside, that’s quite a detail to uh, truncate...).

Secondly...

The cost of learning a shadowy organisation’s secrets was alluded to here...

...with it even further emphasised as the ‘Supreme Leader’ figure’s.

To recap: from the beginning, this ‘little urchin’ dropped a whole bunch of classified information on our rookie detective, threatened his life for knowing it, then gave him the option to join the big, bad organisation for his own safety.

Knowing that Ouma wasn’t actually going to take his life - and was mostly making a point - this tidbit is certainly interesting, and very concerning.

First of all, if Ouma is able to divulge something like that, it would suggest that it doesn’t actually matter if Shuichi ‘joins or not’, because... though he doesn’t know it yet, he’s already one of them, along with [the rest of the Ultimate crew]. What’s more, is Shuichi ‘accidentally’ stumbling upon what appears to be a high profile murder case, in his history. Thus, the propensity to walk headfirst into some classified and dangerous territory, without even realising how.
