Kaku-San-Sei Million Arthur

A journey of new Arthurs begins. Four Arthurs have drawn Excalibur that existed in the era of ‘Kaku-San-Sei Million Arthur.’ – Bard, Mercenary, Merchant and Thief.

However, as the battle against ‘Invaders’ becomes intense in Britain, there is no place for new Arthurs to step in.

While they are training at ‘Hebrides Castle’ located in the north of Britain, the greatest threat begins to cast a shadow over Britain.
