I bursted a gut when he whipped out glow sticks to beat those guys up plus the panels of the concert playing to his fight would make a great visuals/choreography if this gets an anime adaption (a guy can dream). Instafollow from me and thanks for the translations.
The other nice thing about doing his name this way is that in addition to both meaning 'end' (as you said in tl note), you can mentally read his name as 'End of World' which I am totally doing.
