Marina Hebiishi (Destrose/Mardelas) - Rin 霖. Awesome Vocals!!! (B♭4-A5) 

She has serious power...clearly above all the others❤❤❤❤😊😊😊😊🤘🤘🤘🤘🤙🤙🤙

Marina is at the top ,in her vocals.Her singing stirs the emotions in good way.she is one very special lady,in Hard Rock and Heavy metal.

With Fuki (Unlucky Morpheus, LightBringer) , Eye (Mary's Blood, Destrose), Marina (Mardelas, Destrose), Nana (Fate Gear, Reasterisk, Theo Nova) and a few others, Japan currently has the best rock female vocalists in the world.

I could listen to Marina sing all day long!!

Dangerously approaching Floor Jansen(Nightwish) territory talent wise...Kudos😝😝😝🤟🤟🤟🤙🤙🤙❤❤❤

damn.... there must be something in that voice... so mesmerizing... and her looks... wow... she's like a siren that will lure you to....

Lo que Marina hace con su voz es increíble, esa niña podría cantar cualquier cosa, especialmente Metal. Largos años a ella, para que nos siga deleitando con su magia. Aquí en México casi nadie la conoce -ni siquiera los jóvenes- así mejor, pocos somos los elegidos.

Best voice in metal today

❤ MARINA HEBIISHI ❤ I LOVED 😍 GREETINGS FROM ARGENTINA 🇦🇷✌

Rin + Marina = Destrose ...awsome combination!!!

最高のHRHM女性ボーカリスト。大好き。

Wait.. What?!! That last note though. Better than studio version. no doubt

蛇様🐍は本当に最高の方ですよ　 人柄も凄い良くて俺も大好きです！ 会いたいなぁ・・・；；

I love her

I guess this makes her a mezzo-soprano then. Edit: unless she has songs where she sings higher, which is quite possible.
