No schedule. The first 20 or so chapters have a little cringe-inducing English. The story is slow and summoning spells are actually scarcely shown at the beginning.

Old synopsis:

Have you ever heard about him?Of he who was born in the city of mages?He, who once burned a kingdom to the ground?Whose spells did he wave together humbled the gods?Who made men's wildest nightmares pale before those he called from the beyond?The Hypocrite. The Thief. The Mad. The Murderer. The Calamity.History talks about those and more men, and their many deeds.What it doesn't tell is that all of them were only one man.He was known by many names.The Summoner.So, tell me, haven't you heard of him before?It doesn't matter, so listen, as I will tell his story one last time.
