I start my day by exploring Teyvat in Genshin Impact and end it after reorganizing my apartment in Final Fantasy XIV. I am a diehard fan of N64 era games and will forever feel betrayed that Megaman Legends didn't finish. Outside of gaming, I have spend my time collecting manga, collecting anime figures, and watching anime with my naked cat.
