I've been messing around with my Gundam Build Strike HG, then i found that the Build Strike have inner frames, not all the parts have, only the leg and the hand, maybe the Star Build Strike have inner frames, for all of you remember when the Star Build Strike use RG system, it shown when the Gundam hand is glowing it shows an inner frame, when i saw that, i thought that Sei Star Build Strike is not HG (because Hg never have inner frame, but MG does) until i found this, but this is Build Strike, maybe the Star Build Strike have. (Maybe you guys already know this, this is just an information, sorry for the long updates
