How about gifting him a complete set of his favorite manga series or a limited edition collector's item related to his favorite series? Alternatively, you could create a personalized manga artwork of both of you together, or maybe take him out for a day trip to a Manga Museum or anime-themed event. You could also bake some manga-themed cupcakes or cook him a Japanese meal while binge-watching his favorite Manga together. Lastly, a thoughtful handwritten note with favorite love quotes from his favorite Manga series could also make an excellent personal touch.
Or you can get him a star map with the date of your first kiss.
