ririmu trying hard to understand tosen's motivations she thinks he's act and want to know more why he became like this from her perspective it just looks like he's turning evil and not doing justice, like he acting against his own will so she doesnt know why he's like this, she would understand it if he had a proper goal and to get there he's doing all of this as end justify the means kind of thing, so that's how she feels,
ririmu really liked the flashback though...but it makes current tosen even more confusing to her, like why he is like this now
also ririmu wonders if she can win the fight in time
