Your image file is broken, can't see it .. Anyways, Orange Summons you mean this summons? ..

If yes, that summons is obtainable via different ways, you can get them by using your Summoning Scrolls or by buying its fragments in the Redemption Shop .. But some of the Orange or Gold Summon is only obtainable from events like Giant Crustacean and Guy's Tortoise, which is usually at the Time-Limited Shop or Lucky Board ..
