The E-Circular (E-サーキュラー Ī-Sākyurā) is a weapon used by Mashin Chaser whenever he assumes one of his Tune Chaser (武装チェイサー Busō Cheisā, lit. "Armed Chaser") forms using the Chaser Viral Cores, which materializes from the Circular Dynamics (サーキュラーダイナミクス Sākyurā Dainamikusu) on his back and equips him with one of three weapons depending on the core used. Accessed through the Break Gunner, Mashin Chaser can initiate a Full Break (フルブレイク Furu Bureiku) finishing blow with any of his weapons by pressing the Destruction Muzzle and then pulling the Demolition Trigger.
