Okisaba provides an introduction to the nationwide rules of airsoft in Japan, aiming to make the hobby less intimidating for beginners. The crew explain that while individual fields often have their own specific house rules, certain core principles remain consistent across Japan. They emphasize that understanding these basics is essential before worrying about advanced tactics or winning strategies.

The primary rule discussed is the "hit" system, where players must loudly declare when they are struck by a BB and raise their hands to signal their departure from the game. This leads into a discussion about "zombies," or players who ignore hits, which is described as a sure way to ruin the fun for everyone else. Safety is also highlighted, particularly the absolute necessity of keeping eye protection on at all times while inside the field, regardless of fogging or the game ending.

Finally, the talk on the conduct between players, such as avoiding "overkill" by not continuing to shoot a player who has already signaled a hit. The guys also touch upon blind firing and grenade safety, suggesting that players should always look where they are aiming and toss grenades underhand to avoid injuries. They say that as long as players focus on safety and honesty, they can enjoy this long-lasting hobby for many years.
