The thesis imagines a new church type under the post-secular condition, in which religion and secular seek to coexist and share equal importance. Through the establishment of a secularized church, the thesis intends to raised the awareness of the ongoing social phenomenon of secularized religion and its reflection upon architectural discipline. The design of the new church takes Otaku as the touchstone, from which a different type of cultural-social form emerges from the combination of the two elements, the frame as the exhausted form from the past and the soft contents that constantly negotiate within. Through the porosity of the armature and the interactive movement of the pneumatic bubbles, the thesis explores alternatives of church forms in its temporarity and sublimity, and therefore localizes religion back to the public realm.
