Attack on Titan: Monster Bug Capture Plan

Weird Bug, the boss behind the scenes throughout the entire giant world, as a high-latitude creature, even uses the closed loop of the entire world as the ecological circle for his research. And I will bear the mission of exploring the source of all this, not only to find out the hidden secrets, but also to complete the task and "go home". But in order to achieve this goal, I must be extremely careful and proceed cautiously, because once I disturb the Weird Bug and make it abandon the current timeline, I will be trapped in this world forever and cannot leave. Then... The Weird Bug Capture Plan begins!
