Just wanted to express some of my CREATIVITY.

Denkiteki 伝説の精神 (Legendary Soul)
Silver blade, white guard, and black hilt. The blade is very long, and the hilt is pretty long too.
Say "歴史を作りなさい (Meiku iwaku)" meaning "Make History" to release shikai.

Shikai - The silver blade grows longer than its original form and the guard then disappears. The hilt turns into a black tube which covers the user's arm, acting as armor for the wielder. The primary ability for the shikai form is "精神 弾丸 (ki dangan)" which is a spirit bullet that rapidly fires from the blade. The second ability is "エネルギー 雨 (seishou ame)" which is energy rain. The wielder points Denkiteki to the air and energy rains pours down the victims, hitting them with high amounts of energy. In shikai, Denkiteki boosts speed.

Bankai 伝説 銃 殺害者 (Legendary Gun Slayer) - The guard takes the form of one of those bullet barrels that revolvers have. The barrel has 6 energy chambers, which is for the ability of the blade which can shoot very high blasts of energy at a very fast speed. After six shots, each barrel has to regenerate energy bullets in 30 seconds. The hilt turns at a 60 degree angle which makes the sword mimic the structure of a gun. The blade is very long and shines very violently. It boosts kidou, strength and speed. Its abilities are a much stronger form of its shikai abilities.
