Busou Renkin is a good old-fashioned power-up, beat-em-down, get-the-girl anime. While it's not innovative and probably won't leave much of a lasting impression, Buosu Renkin sports strong, memorable characters and a kickass opening (the best part of the show) matched only by GaoGaiGar's famous "Yuusha-Oh Tanjou". It puts the "man" and "romance" and is a must-see for any shounen fan.
