Swimsuits and keys.
Another week, another Nisekoi, except this time it’s swimsuit time. This is, after all, a high-school romcom, and every high-school romcom needs a swimsuit episode, whether it is at the beach or the pool. However, this fifth episode of Nisekoi, appropriately titled “Swimming”, manages to be more than just fanservice. Don’t get me wrong, “Swimming” had more fanservice than Nisekoi episodes one through four combined, but it also contained some vital plot development that will undoubtably have important ramifications in future episodes. Well, as important as plot development gets in Nisekoi, at least.
