Harmonious life(Multiverse travel fic with a lot of philosophy!))

Life is such a beautiful thing... We can live happily and share our happiness with others. In a nutshell: Multiverse travel, chaotic shenanigans, a lot of philosophical deep meaning...yeah, better in my head! Sooo, one buddy, who enjoyed philosophy, introspection, meditation and spiritual way of world, wanted to have an adventurous life... and has an accidental meeting with a door for multiverse-travel - Хумгат from Max Frei's "Labyrinths of Echo". .......................... Worlds: Spice and a Wolf, Merlin, Omamori Himari, Harry Potter, Nurarihyon no mago, Fate series... other worlds would be added later. Prospective worlds: One piece, Star Wars, Mahouka koukou no rettousei, Fairy Tail, Witcher, Percy Jackson and Olympians, Highschool DxD(I know, I know but the sheer potential for shenanigans!), Marvel(Dambledore can have his birdy, we would pick up the most girly phoenix! ), Battle Through The Heavens(BTTH), World of Warcraft...
