Shinchou Yuusha: Kono Yuusha ga Ore Tueee Kuse ni Shinchou Sugiru

Synopsis

When Ristarte and Seiya flee to the Divine Realm, Chaos Machina decides to attack Edona. Seiya learns time moves differently in the Divine Realm. Two days later, Ristarte receives a message from Chaos Machina demanding that they return or she will execute one resident every ten minutes. Seiya is unconcerned as ten minutes on Gaeabrande is roughly sixteen hours in the Divine Realm. When he is finally ready, Ristarte is shocked to learn he has reached level 21. They return to Gaeabrande where Chaos Machina realizes all Seiya's stats are higher than hers, so she transforms into her true form. When Seiya survives, it is revealed that he has been using the Fake Out skill the whole time to hide his true level, which is actually at level 37. Seiya then destroys Chaos Machina, which earns him and Ristarte the town's admiration. However, concerned that Chaos Machina might regenerate, Seiya blankets her charred remains with explosions. In the process, Edona is also destroyed and the formerly thankful Mayor of Edona now tearfully begs them to leave. When Ristarte and Seiya return to the Divine Realm, Ristarte wonders how the situation with Seiya is going to work out.
