Hey /m/, first time poster. I dont know if this board allow request so i'm just going to post it and hope the jannies have mercy on me. So here are some feature I still remember about it
> A mecha anime ( of course )
> The production looks 90s to early 2000s, the theme is kinda dark
> In intro, there was an girl with long pink hair. Later, in the series, upon her first interaction with the protag, she may change or take something off her clothes and make him blush
> Protagonist is a high schooler ( he may wear glasses ) and throughout the series it's mostly him control a mecha
> The first ( or also second ) episode has a black short hair girl whose task was to find the protag. Later, in the series she and protag develop feeling and they kiss each other before the big final fight with the protag promise he will be back
>there was one episode where the plot start with the regularly appears male doctor who gave a female collage a necklace make from a green crystal. Later, the crystal turn her into a monster and the protag has to fight her.
I think that's all the detail I remember. When thiis was air in my country it was 10+ years ago and it aired very late so it's impossible to trace it asking my peers. I also can't find information about it using the network website because all the data was scrap.I guess this board is one of my few only hopes, I would really appreciate it if someone can help me
