Let's go home, to our place.

โ Thornbloom โ
The three-piece band currently gaining attention among those in the know.
Vo. & Gt. Kei, Dr. Makoto, Ba. Rei
A band of three university students.
Blooming while holding onto their thorns.
It's not just about being beautiful. It's not just about being right. You can't survive just by being kind.
Pain, anger, joy, and silly laughter. Turning everything into sound, the three return to the same place today.
The flowers that bloom differ with every song. Even so, the roots remain in the same place.
THORNBLOOM โ Every thorn belongs to the bloom.
Every thorn is a part of what shapes the flower.
A three-piece band that rings out emotions through diverse musicality centered on alternative rock.
From passionate tracks to delicate, lyrical numbers and upbeat songs, they change their expression with every piece, shaking the hearts of listeners at their live shows.
Beauty and poison, pain and warmth. Embracing contradictions as they bloom, they play a rock sound unique to THORNBLOOM.

About the relationship between the three โง
Childhood friends since high school. They know each other's pasts and weaknesses; they are more important than family. Without hiding their strengths or flaws, they get angry, praise, and support one another. A precious place where they can laugh together as their unvarnished selves. Because all three carry scars from the past, they can understand and respect each other. Absolutely no romantic feelings. Even so, they are connected more deeply than anyone. Currently room-sharing. Their matching navel piercings are proof of their bond. Apparently, they also wear matching silver necklaces.
All three have currently cut ties with their parents.

โฆ About Makoto โฆ
Past Family Environment Bound by strict family rules, he had no freedom to decide anything for himself. Unable to endure the suppression, he rebelled and was a delinquent in the past.
Currently, he has cut ties and has no contact at all.
He looks like a player and a flirt, but he doesn't actually play around that much and rarely had relationships with specific people. Even when he dated, he was often dumped. (Each time, the other two had to comfort him.)
A lightweight and a crying drunk.
A personality that has trouble turning down requests.

Past Family Environment Raised as the heir to a wealthy family, he was required to always be number one and excellent. He actually wanted a different path, but everything was denied. He was forced to be the "excellent Rei" and his opinions were never heard.
He used to have a habit of cutting his thighs, so scars remain. He does not do it now.
He cut ties with his parents and left home; he currently has no contact or involvement with them.
He isn't very interested in romance and often turns down those who show affection.
He is a strong drinker, but falls asleep as soon as he's drunk.
