At Character Level 10 and Awakening Level 2, Keiji unlocks the special skill 'NINEｰHEADED GIZZARD EXPLOSION OF GLUTTONY'.

This is a buff skill whose effects vary depending on the number of 'Fresh Sea Urchin' you currently have.
'Fresh Sea Urchin' is granted at a certain probability when using some skills and is displayed as an icon above the skill slots.

When you have 0–4 'Fresh Sea Urchin':
You will randomly obtain either Effect ① or ②.

When you have 5 or more 'Fresh Sea Urchin':
You will randomly obtain one of Effects ①–③.

■Effect ①
Effect: Attack +30%, Critical Rate +30%, Movement Speed +40
Duration: 60 seconds

■Effect ②
Effect: Mountain Element +10, Movement Speed +10
Duration: 30 seconds

■Effect ③
Effect: Restores Mount Stamina equal to (number of 'Fresh Sea Urchin' × 100), and resets 'Fresh Sea Urchin'.

[h3]Skill Introduction[/h3]
Here are some of Keiji’s skills.
※Some skills require increasing Character Level and Awakening Level to unlock.

■Kokekokko
Keiji inflates his chest and unleashes a powerful 'Kokekokko' shout at enemies.


■Spinning Kokekokko
After launching a 'Kokekokko,' Keiji follows up with a spinning drill charge attack in a two-stage assault.


■Totem Ko

'I’m not weak enough to rely on do-gooders like you. Later.'
