This study seeks to demystify one of a niche subculture of extreme female fans and mavens known as “Fujoshi” who get really into animation, comic, novel and so on. They call themselves self-mocking term “Fujoshi” and are willing to draw⁄read fanzines that are an underground hobby focused on romantic or homosexual relationships between male characters from various media texts. In this paper, I describe how they construct their identities and social relations through narrative and practice. First I frame this work as an effort to think the differentiation between “self” and &ldquoidentity”. Then I show the core characteristic of “Fujoshi” groups is the issue of hiding identity. The assumption has been in subcultural studies that the embodied external identity display in the face of mainstream culture is foundational. But “Fujoshi” culture does it differently. Although they make their identities invisible in everyday lives, that hiding practice paradoxically makes their identities visible in “Fujoshi” community. The other area that I found interesting was their ironical communication. Because they believe that “Fujoshi” activities are considered to be inferior to the &ldquonormal” females, they express their identities self-deprecatingly. I think this practice is a defensive communication against prejudice and is also a strategy to present their identities paradoxically.

This paper contains a series of essays which form a synopsis of my research career, which has been dedicated to orogenic and metamorphic processes in plate boundaries. It also presents my future research directions and latest investigations into simplifying the complexity of metamorphic rocks, their field observations, and associated convergent plate margin dynamics.

 Slab dehydration beneath forearcs and arc has been one of the most exciting problems in the field of convergent plate margin dynamics in recent decades. Orogenic and metamorphic processes are closely related. In the subduction zones, the fluid-mediated processes primarily control the crust-to-mantle transfer of volatiles, redox states of the wedge mantle peridotite and arc magmas, flux-melting to generate arc magmas, and seismicity. Although the methods of classical metamorphic petrology, based on phase equilibrium calculations, and the application of conventional geochronology continue to provide the opportunities to link high-pressure and ultra-high-pressure metamorphism to geophysical observations today, advances in geochemical techniques have great potential for key geological markers in global convergent margins. For example, recent analytical techniques and applications used in studies of metamorphic rocks, such as in-situ Li-B-Sr-Pb spot isotope analyses of jadeite, serpentinite, lawsonite, etc., evaluate hydration and dehydration along the subduction channels and subsequent slab-mantle interaction, and visualize more realistic ancient Pacific-type convergent margins. The scientific value of subduction-zone rocks and crustal rocks are not limited to their worth for geochemistry: Some metamorphic rocks and minerals are important for all realms of geological sciences, from nano-scale kinetics to the scale of mountain building events. Consequently, collaborative exchange among geoscientists, through the application of applying different approaches, tests, and challenges, to address problems related to plate boundaries in the future.
