What does this mean?
Bokura Wa Shonen Tantei-Dan
If we're going for something like:
"We are the torpedo boyz."
An intermediate translation might be:
"We are boys boat weapon."
Therefore:
Bokura - we (some boyz)
Wa - topic marker (we're talking about ourselves)
少年 Shonen - boy
短艇 Tantei - boat
Dan - weapon?
