There is a chance for a pillar to spawn in some rooms; hasn't worked for me in the 1st room, but in most other rooms (library probs wont spawn since it's kinda rigged), you have to clear out enemies, then you use a chip for mechanical tentacle thingy, and then u can go back to pub/bar and buy more chips to use; they usually give you a run buff with the bonus of a lewd scene; the tf isn't permanent, but the maid one is probably the best so far in terms of actual tfs in the game.
