闘姫淫縛2 -凌触戦記 エナッスク-

Part 2 in the favourably received tentacle monster assault ADV.
In this title, fantasy RPG style characters are thoroughly assaulted by the tentacle monsters.

The tentacle monster ghost Nidhog breaks free of the seal of the heavenly temple that binds his being, and escapes to a continent on the illusional world. He sets out to assault and kill would-be avenger Valkyrie, turning the tables on Valkyrie when he himself is set on hunting and killing him. Also, Nidhog has set his sights on a new trophy...

Receiving the ultimate pleasure, in order to make an offering that wrings out an aura that will become one's nourishment...
