Re:member title names

Each part of the 『Re:member』 titles has a Re:vale member's name, beginning
with Banri (万理) in 'Banri Ikkuu' (万理一空), Yuki (千) in 'Senko Fuma'(千古不磨),
and Momo (百) in 'Hyakusai Mukyuu' (百載無窮).
I've complied the weblio, jisho, and yojijukugo jiten online definitions here
since they're all super meaningful!

『万理一空』
Quoted from a book by swordsman Miyamoto Musashi, the phrase "banri-ikkuu"
means "everything in this world is under the same sky" and signifies allyship.
It's a logical line of thought: "No matter where you go, the world is still the
same." On the other hand, it may also be used in the context of mental fortitude,
i.e. "No matter where I go, I'll be focused on the same goal and never stop
working for it."

『千古不磨』
"Senko-fuma" means permanence, immortality, eternity-- something that'll never
disappear. It may also describe something that'll never come to an end and
continue to be passed on. "Senko" refers to the faraway past, but can also mean
something that has continued from the faraway past until the present. "Fuma" indicates
that something won't be worn down. It is often used in the context of the the fine arts,
crafts, or traditions, in that they will continue to be inherited and passed on.

『百載無窮』
"Hyakusai-mukyuu" means "something that'll never disappear." "Hyakusai" (百載) as written
in the compound can also be written as 「百歳」, which in turn means 'a hundred years.'
This signifies eternity, perpetuity, immortality​. Likewise, "mukyuu" means eternity,
infinitude, immortality​. The phrase refers to how heaven and earth are unchanging,
everlasting.
