Zoids Wild 2 is releasing its second manga volume on June 26th! This manga has an excellent style, so I highly recommend picking it up. You can get a copy at Amazon Japan for 670 yen (about $6). Amazon JP requires a separate account from your US amazon account, but you can pay with your normal cards. Some chapter previews were posted over on twitter showing off the more recent chapter art, including the Zero Grizis.
