Summary
After saving another world as a teen, Hizaki Shiou was sent back home. Three years later, he’s summoned once more—this time to stop the secret society “Helheim” from causing chaos. To his horror, he realizes the group was actually founded by his own chuunibyou past self, when he called himself the Corpse King. Now, someone is misusing the name and disgracing his legacy. Teaming up with his former elite squad, the Hakkai, he sets out to clear Helheim’s reputation. Their mission begins in the famine-stricken Steel City of Gagiul, where they must rescue a pale noble’s daughter and restore order.
